The application deadline for fall 2015 admission will be December 15, 2014. All applications and supporting materials must be submitted online before the deadline. Please check the
Harvard Graduate School of Arts and Sciences (GSAS) website
for Prospective Students for more information on the application process.
Preparing for the Application
The statement of purpose for graduate applications is very different from writing a personal essay. It is neither a biographical sketch nor a reflection on your decisions to enter the field. It should be written for a particular audience: The admissions committee, which consists of faculty members in the department. Your statement should convince the committee that you are able to communicate effectively and with a deep understanding of mathematics.
Request three letters of recommendation from faculty or others qualified to evaluate your potential for graduate study in mathematics. The letters must be submitted online and by the application deadline.
The Department requires all applicants to submit GRE Mathematics Subject Test scores. Applicants should check on the ETS website for test dates in their area to insure the scores will be submitted before the application deadline. While the admissions committee reviews all applications submitted by the deadline, missing math subject test scores are one less data point available to evaluate the application. Depending on the applicant pool and the strength of the application materials, the missing subject test scores may put the application at a disadvantage.
The Graduate School requires scores to be submitted for the General Test of the Graduate Record Examinations (GRE).
Applicants whose native language is other than English and who do not hold the equivalent of a US Bachelor degree from an institution at which English is the language of instruction must submit scores from the Internet based test (IBT) of the Test of English as a Foreign Language (TOEFL).
The Graduate School requires applicants to upload acopy of their undergraduate transcripts. Additionally, applicants must submit a hard copy of the official university/college transcript bearing the seal of the institution and signature of the registrar or appropriate official.
PhD Program in Pure Mathematics
The department does not grant a terminal Master's, but a Master's degree can be obtained "on the way" to the PhD by fulfilling certain course and language exam requirements.
In general, there is no transfer status application to the Graduate School of Arts and Sciences or to the Department of Mathematics. No formal credit is given for an MSc or MA earned elsewhere. All applicants are considered to be applying as first year graduate students. The only difference Master's study may make is to better prepare a student for the Qualifying Exam, which is required of all first year students.
All graduate students are admitted to begin their studies in the fall term. We plan on an entering class of about ten to twelve students. Since we normally receive over two hundred applications, the competition is keen.
Funding Graduate Study
Applicants are urged to apply for all funding available to them. If no outside funding is available to the applicant, financial aid in the form of scholarships, research assistantships, and teaching fellowships is available. In general, students who do not have outside support will get scholarship support in their first year, but students are required to act as a teaching fellow for one half course (i.e. for a one term course) in their second through fourth years and for two half courses if they stay for a fifth year.
The department provides continuing students with summer support in the amount of $4,202. In addition, a number of teaching opportunities are available during the summer.
Junior and visiting faculty interests comprise a
diverse and important addition to the department. As these
appointments vary in length from one term, on the part of
visitors, to threeyear appointments as a Benjamin Pierce
Lecturer on Mathematics, Assistant Professor
of Mathematics, they will be listed annually in
the courses of instruction.

The department strongly recommends applicants to seek out and apply for all sources of financing availalbe for graduate study. Recommended sources for funding US graduate students are NSF Graduate Fellowships and NDSEG Fellowships. Applicants from the UK are urged to also apply for the Kennedy fellowships and applicants from UK, New Zealand, Canada and Australia, for Knox fellowships. International students may apply for the Fullbright IIE or any home country fellowships available for study abroad.

Guide To Graduate Study
The PhD program of the Harvard Department of
Mathematics is designed to help motivated students to develop their
understanding and enjoyment of mathematics. It seems to be generally
the case that enjoyment and understanding of the subject, as well as
enthusiasm in teaching it, are greater when one is actively thinking
about mathematics in one's own way. For this reason, a PhD dissertation
involving some original research is a fundamental part of the program. The
stages in this program may be described as follows:
The word "help" (in the opening sentence above) is to emphasize that
the student is expected to take the initiative in pacing him or herself
through the PhD program. In theory, a future research mathematician
should be able to go through all three stages with the help of only a good
library. In practice, many of the more subtle aspects of mathematics, such
as a sense of taste or relative importance and feeling for a particular
subject, are primarily communicated by personal contact. In addition,
it is not at all trivial to find one's way through the everburgeoning
literature of mathematics, and one can go through the stages outlined
above with much less lost motion if one has some access to a group of
older and more experienced mathematicians who can guide one's reading,
supplement it with seminars and courses, and evaluate one's first attempts
at research. The presence of other graduate students of comparable ability and
level of enthusiasm is also very helpful.
The University requires a minimum of two years academic residence
(16 halfcourses) for the PhD degree. On the other hand, five years in
residence is the maximum usually allowed by the Department.
Most students complete the PhD in four to five years. Please review the
program requirements timeline.
There is no prescribed set of course requirements, but the department
runs several introductory graduate courses (e.g. Math 212a, 213a, 230a,
231a, and 232a) to help students acquire the necessary broad basic
background in mathematics. Students are required to register and enroll
in four courses each term to maintain full time status with the Graduate
School of Arts and Sciences, but students may substitute TIME for one
course when teaching or engaged in independent study or research.
The department gives a biannual qualifying examination at
the beginning of the fall and spring terms. One's first goal should be
to bring one's basic knowledge up to such a point that one can pass the
qualifying exam. Some students are able to pass as soon as they enter,
and all are required to take the exam at the beginning of the first term.
Those who do not pass simply try again on the following occasion. All
students are expected pass the qualifying exam before the end of their
second year.
The qualifying examination covers algebra, algebraic geometry, algebraic
topology, complex analysis, differential geometry, and real analysis.
More details about the qualifying exams can be found
here.
After passing the qualifying exam students are expected to find a PhD dissertation adviser.
The minor thesis: The minor thesis is complementary to the qualifying exam. In the course of mathematical research, the student will inevitably encounter areas in which he or she is ignorant. The minor thesis is an exercise in confronting gaps of knowledge and learning what is necessary. The student chooses a topic outside her or his area of expertise and, working independently, learns it well and produces a written exposition of the subject.
The topic is selected in consultation with a faculty member, other than the student's PhD dissertation adviser, chosen by the student. The topic should not be in the area of the student's PhD dissertation. (For example, a student working in number theory might do a minor thesis in analysis or geometry). At the end of three weeks time (four if teaching), the student will submit to the faculty member a written account of the subject and be prepared to answer questions on the topic.
The minor thesis must be completed before the start of the third year in residence.
Mathematics is an international subject in which the principal languages
are English, French, German, and Russian. Almost all important work is
published in one of these four languages. Accordingly, every student is
advised to acquire an ability to read mathematics in French, German,
and Russian and is required to demonstrate it by passing a twohour,
written language examination in two of these three languages. Usually students
are asked to translate one page of mathematics into English with the
help of a dictionary. A student who thinks it is pertinent to
his or her field of interest may substitute Italian for one of the languages
mentioned above. The first language requirement should be fulfilled by
the end of the second year; the second language requirement should be
fulfilled by the end of the third year. More information on the graduate
program requirements timeline can be found here.
Upon completion of one language exam and having taken eight real courses
(not TIME), students can apply for a continuing Master's Degree, which may
be useful for higher paying summer jobs.
Most research mathematicians are also university teachers. In
preparation for this role, all students are required to participate
in the department's teaching apprenticeship program and to
complete two semesters of classroom teaching experience,
usually as a teaching fellow. During the teaching apprenticeship the student
is paired with a member of our teaching staff. The student will attend
some of the adviser's classes and then prepare (with help) and
present his or her own class, which will be videotaped. The apprentice will
receive feedback from the adviser and from members of the class.
Teaching fellows are responsible for teaching calculus to a class of about
25 undergraduates. They meet with their class three hours a week. They
have a course assistant (usually an advanced undergraduate) to
grade homework and to take a weekly problem session. Usually there
are several classes following the same syllabus and with common
exams. There is a course head (a member of our teaching staff)
who will coordinate the various classes following the same
syllabus and who is available to advise teaching fellows. Sometimes
graduate students also act as graduate course assistants for
advanced courses or run tutorials for small groups of undergraduates
studying advanced subjects not taught in regular courses.
How a student goes through the second and third stages of the program varies considerably
among individuals. While preparing for the qualifying examination or
immediately after, the student should begin taking more advanced
courses to help with deciding on a field of specialization. Unless
prepared to work independently, she or he should choose a field that
falls within the interests of a member of the faculty who is willing
to serve as thesis/dissertation advisor. Members of the faculty vary a
great deal in the way that they go about thesis/dissertation supervision,
and the student should take her or his own needs in this direction into
account as well as the faculty member's field in making a decision. Some
faculty members expect more initiative and independence than others,
and they vary in how busy they are with other students. The student
must take the initiative to ask a professor if she or he will act as the
dissertation advisor. If one has trouble in deciding under whom to work,
it is possible to spend a term reading under the direction of two or
more faculty members simultaneously on a tentative basis. The sooner
a decision is made the sooner the student can begin reaearch.
Students should have a provisional advisor by the second year.
It is important to keep in mind that no technique has been discovered
for teaching students to have ideas. All that the faculty can do is to
provide an ambiance in which one's nascent abilities and insights
can blossom. Moreover, PhD dissertations vary enormously in quality,
from hard exercises to highly original advances. Finally, many very
good research mathematicians begin very slowly, and their dissertations
and first few papers could be of minor interest. On the whole, we feel
that the ideal attitude is: (1) a love of the subject for its own sake,
accompanied by inquisitiveness about things which aren't known; and
(2) a somewhat fatalistic attitude concerning "creative ability" and
recognition that hard work is, in the end, much more important.
 Acquiring a broad basic knowledge of mathematics on which to build a future mathematical culture and more detailed knowledge of a field of specialization.
 Choosing a field of specialization within mathematics and obtaining enough knowledge of this specialized field to arrive at the point of current thinking.
 Making a first original contribution to mathematics within this chosen special area.
The Qualifying Exam
The qualifying exam is designed to measure the breadth of a student's
knowledge in mathematics. Passing the exam early is mainly an indication
that a student has attended an undergraduate university with a broad
undergraduate program in mathematics. It is not a good predictor of the
quality of the eventual PhD dissertation.
A student may take the qualifying examination any number of times,
beginning in the first term. The exam may prove a useful diagnostic in
helping to identify areas in which a student's knowledge is weak. There
is absolutely no stigma attached to taking the exam several times, but
students are expected to pass the examination by the second
year in residence in order to begin more specialized study leading to
research work.
Before passing the qualifying exam, students should enroll three beginning
200 level (or 100 level) math courses each term and may substitute TIME
for one course to prepare for the exam.
The exam is given at the beginning of each term. It consists of three,
threehour papers held on consecutive afternoons. Each paper has six
questions, one each on the subjects: Algebra, Algebraic Geometry,
Algebraic Topology, Differential Geometry, Real Analysis and Complex
Analysis. Each question carries 10 points. In order to pass in each
subject, a student must obtain at least 20 of the available 30 points
in that subject. Students are considered to have passed the qualifying
exam when they have passed in all six subjects (120 of 180 points) in one
sitting, or they have passed at least four subjects in one sitting and
obtained an A or A grade in the basic graduate courses corresponding
to the subject(s) not passed. Students are expected take the suggested
course(s) at the first opportunity.
Once the qualifying exam has been passed, students no longer need to
take math courses for a letter grade and may elect to receive the grade
(EXC) excused. Students should inform the instructor at the beginning
of the term if they are electing to take (EXC) as a grade.
The Qualifying Exam Syllabus
The questions on the qualifying exam aim
to test a student's ability to solve concrete problems by identifying
and applying important theorems. The questions should not require great
ingenuity. In any given year, the exam may not cover every topic on the
syllabus, but it should cover a broadly representative set of topics
and over time all topics should be examined.
The syllabus is on a seperate page.

Teaching Requirements
Every student, whether or not they have outside
support, is required to have two terms of classroom teaching experience
as preparation for their likely future role as teachers.
For those students without outside support: In the first year, students automatically receive an offer of the full departmental stipend with no obligation to teach. The department offers second, third and fourth year students half the departmental stipend without an obligation to teach, and students are required to teach to cover the other half of the stipend. However, the department caps the amount of teaching students are required to do: If a student teaches one section of calculus, or the equivalent, the department will supplement the stipend up to the full stipend. Fifth year students are expected to teach to cover the full stipend. Again, the department caps the teaching required: If a student teaches two sections of calculus, or the equivalent, and the pay does not support the annual stipend, the department will supplement the stipend up to that year's level. Students may arrange to teach twice in an earlier year to reduce teaching in the final year.
Work restrictions on student visas may limit international student teaching.
Please check with the Graduate Program Administrator before finalizing
your teaching plans.

Equivalence is based on what the department perceives to be the time
commitment of a teaching job. We consider the following to be equivalent
to one section of calculus:
We consider the following to be equivalent to two sections of calculus:

We consider the following to be equivalent to two sections of calculus:

There are other possibilities, which will be allowed on an ad hoc basis,
but this list gives an idea of what is expected.
Students with outside support available in their first year are expected to take it in their first and second year. Students who choose to defer outside fellowship support to a later year will need to teach twice in an earlier year to cover their full stipend in the deferral year. For instance, a student with one remaining year of outside fellowship support who chooses not to take the funding in their fourth year, will need to teach two sections of calculus or the equivalent in their fourth year in order to receive the full departmental stipend. Similarly, a student with two remaining years of outside fellowship support who chooses not to take the funding in their third year, will need to teach two sections of calculus or the equivalent in their third year in order to get the full departmental stipend. The department's teaching staff helps students find appropriate teaching jobs. While we would like to accommodate student's teaching preferences, the teaching staff works under many constraints. It is necessary to balance student preferences with those of other graduate students and the needs of the department. Students who have done a conscientious job on previous teaching assignments are more likely to get their preference in subsequent years. Students need to make teaching plans well in advance and in consultation with the teaching staff. Students should not change their teaching commitments at short notice. Students making satisfactory academic progress may teach beyond the minimal requirement outlined above. Students who are not required to teach as part of their funding package may teach if jobs are available. Pay for additional teaching will supplement other sources of funding. Students must take the initiative to find additional jobs. In assigning teaching positions, first preference will be given to those required to teach for funding. After that, positions will be allocated to those with the strongest teaching credentials. Below are some examples of 10month stipends for 2014/2015 academic year:

Student D in year 3 GCAs two math courses and receives:
 
Student E in year 4 without outside support decides not to teach and
receives:
 
Student F in year 5 teaches two sections of calculus
and receives:

The department provides continuing students with summer support in the amount of $4,202. In addition, a number of teaching opportunities are available during the summer.
