## Spring Tutorial 2018

### Infinitary Methods in Mathematics

 Description: The field of set theory was born out of Cantor's discovery of infinite ordinal and cardinal numbers in the late 19th century. These number systems are now central to almost all modern research in mathematical logic. The subject of this tutorial, however, is the applications of the theory of ordinal and cardinal numbers outside of mathematical logic. The course will therefore touch on several areas of mathematics, including algebra, topology, analysis, game theory, and combinatorics, with the common theme that the proofs will make essential use of infinitary techniques. Prerequisites: The course assumes no prior knowledge of set theory or logic, but a basic knowledge of abstract algebra and point-set topology are recommended. Math 122 and 131 more than suffice.

## Fall Tutorial 2017

### Arithmetic of Elliptic Curves

 Description: This tutorial is an introduction to the arithmetic of elliptic curves. After introducing several equivalent definitions of elliptic curves, we will prove the Mordell-Weil theorem, which states that for an elliptic curve defined over a number field, the set of rational points forms a finitely generated Abelian group. Then we will go into the theory of complex multiplication, and hopefully will have time to discuss more advanced topics including Selmer groups, Tate curves, etc. The first half of the material overlaps heavily with the tutorial in the previous year. Prerequisites: Students should be familiar with basic algebraic number theory. Having taking the undergraduate algebraic geometry class would be helpful, but not required. Though it might be a good idea to take this and algebraic geometry as the same time. Contact: Zijian Yao, zyao@math.harvard.edu)
