Lie algebras, deformations, and Galois theory in characteristic p.

HARVARD-MIT ALGEBRAIC GEOMETRY

March 16, 2021      4:30 pm
Speaker: Lukas Brantner

We introduce a derived version of Lie algebras in characteric p and describe two recent applications: first, we use them to classify infinitesimal deformations, generalising the Lurie-Pridham theorem in characteristic...

Exploring new scientific frontiers with programmable quantum systems

MATHEMATICAL PICTURE LANGUAGE

March 16, 2021      10:00 am
Speaker: Mikhail Lukin - Harvard University

I will discuss recent developments at a new scientific interface between quantum optics, quantum many-body physics, information science and engineering. Specifically, I will focus on two examples at this interface...

Existence of CM lifts for points on Shimura varieties

NUMBER THEORY

March 10, 2021      3:00 pm
Speaker: Keerthi Madapusi Pera - Boston College

I'll explain a very simple proof of the fact that K3 surfaces of finite height admit (many) CM lifts, a result due independently to Ito-Ito-Koshikawa and Z. Yang, which was...

Gromov–Witten invariants of some non-convex complete intersections

DIFFERENTIAL GEOMETRY

March 9, 2021      8:00 pm
Speaker: Nawaz Sultani - University of Michigan

For convex complete intersections, the Gromov-Witten (GW) invariants are often computed using the Quantum Lefshetz Hyperplane theorem, which relates the invariants to those of the ambient space. However, even in...
