Introduction to works of Takuro Mochizuki
I will give examples and motivations, about the local
systems/Higgs bundles correspondence, the case of variations of
Hodge structures and the case of irregular singularities. I hope
this will help to enjoy the forthcoming lectures of T.

On the notion of genus for division algebras and algebraic groups
Andrei Rapinchuk
Let $D$ be a central division algebra of degree $n$ over a field
$K$. One defines the genus gen$(D)$ of $D$ as the set of classes
$[D']$ in the Brauer group Br$(K)$ where $D'$ is a central division
$K$-algebra of degree $n$ having the same...
Two-bubble dynamics for the equivariant wave maps equation
Jacek Jendrej
I will consider the energy-critical wave maps equation with
values in the sphere in the equivariant case, that is for symmetric
initial data. It is known that if the initial data has small
energy, then the corresponding solution scatters. Moreover...
The three pillars of statistical machine learning: then and now
In this (short and informal) talk I will present the three
fundamental factors that determine the quality of a statistical
machine learning algorithm. I will then depict a classic strategy
for handling these factors, which is relatively well...
Structure theorems for intertwining wave operators
We will describe an implementation of the Wiener theorem in
$L^1$ type convolution algebras in the setting of spectral theory.
In joint work with Marius Beceanu we obtained a structure theorem
for the wave operators by this method.
Nonlinear descent on moduli of local systems
Junho Peter Whang
In 1880, Markoff studied a cubic Diophantine equation in three
variables now known as the Markoff equation, and observed that its
integral solutions satisfy a form of nonlinear descent.
Generalizing this, we consider families of log Calabi-Yau...
Motivic correlators and locally symmetric spaces III
According to Langlands, pure motives are related to a certain
class of automorphic representations.Can one see mixed motives in
the automorphic set-up? For examples, can one see periods of mixed
motives in entirely automorphic terms? The goal of...
Cap-sets in $(F_q)^n$ and related problems
A cap set in $(F_q)^n$ is a set not containing a three term
arithmetic progression. Last year, in a surprising breakthrough,
Croot-Lev-Pach and a follow up paper of Ellenberg-Gijswijt showed
that such sets have to be of size at most $c^n$ with $c q...
Cohomology of arithmetic groups and Eisenstein series - an introduction (continued)
10:00am|Physics Library, Bloomberg Hall 201
I intend to cover some basic questions and material regarding
the phenomena in the cohomology of an arithmetic group "at
infinity" when the corresponding locally symmetric space
originating with an algebraic $k$-group $G$ of positive $k$-rank is
non...
Weinstein manifolds through skeletal topology
Laura Starkston
We will discuss how to study the symplectic geometry of
$2n$-dimensional Weinstein manifolds via the topology of a core
$n$-dimensional complex called the skeleton. We show that the
Weinstein structure can be homotoped to admit a skeleton with
a...
