Harvard-MIT Algebraic Geometry: The top-weight cohomology of A_g

SEMINARS, HARVARD-MIT ALGEBRAIC GEOMETRY

November 29, 2022      3:00 pm
Speaker: Juliette Bruce - Brown University

I will discuss recent work calculating the top weight cohomology of the moduli space A_g of principally polarized abelian varieties of dimension g for small values of g. The key...

CMSA Topological Quantum Matter: Continuum field theory of graphene bilayer system

SEMINARS, CMSA EVENTS

November 23, 2022      9:00 am
Speaker: Jian Kang - School of Physical Science and Technology, ShanghaiTech University, Shanghai, China

The Bistritzer-MacDonald (BM) model predicted the existence of the narrow bands in the magic-angle twisted bilayer graphene (MATBG), and nowadays is a starting point for most theoretical works. In this...

Gauge Theory and Topology: Monopoles and families of contact structures

Gauge Theory and Topology Seminar, SEMINARS

November 18, 2022      3:30 pm
Speaker: Juan Muñoz-Echániz - Columbia University

Beyond the tight/overtwisted dichotomy, 3-dimensional contact topology would appear to be dominated by flexibility: a central result of Eliashberg and Mishachev says that the contactomorphism group of the standard contact...

Algebraic Dynamics: Stable Algebraic Families of Rational Maps

ALGEBRAIC DYNAMICS, SEMINARS

November 17, 2022      4:00 pm
Speaker: Rafael Saavedra - Harvard University

McMullen proved that a stable family of rational maps is either trivial or all its members are Lattès. His proof relies on Thurston's theorem on postcritically finite maps, which uses...

CMSA Active Matter Seminar: Dynamic and multicolor electron microscopy

SEMINARS, CMSA EVENTS

November 17, 2022      1:00 pm
Speaker: Max Prigozhin - Harvard University

My lab is developing biophysical methods to achieve multicolor and dynamic biological imaging at the molecular scale. Our approach to capturing the dynamics of cellular processes involves cryo-vitrifying samples after...
