Mirrors of curves and their Fukaya categories
9:00am|https://princeton.zoom.us/j/745635914

Homological mirror symmetry predicts that the derived category of coherent sheaves on a curve has a symplectic counterpart as the Fukaya category of a mirror space. However, with the exception of elliptic curves, this mirror is usually a symplectic...

Forecasting Epidemics and Pandemics
Roni Rosenfeld
3:00pm|Remote Access Only - see link below

Epidemiological forecasting is critically needed for decision making by national and local governments, public health officials, healthcare institutions and the general public. The Delphi group at Carnegie Mellon University was founded in 2012 to...

Iwasawa theory and Bloch-Kato conjecture for unitary groups
9:00am|https://theias.zoom.us/j/959183254

We describe a new method to study Eisenstein family and Iwasawa theory on unitary groups over totally real fields of general signatures. As a consequence we prove that if the central L-value of a cuspidal eigenform on the unitary group twisted by a...

Conley's fundamental theorem of dynamical systems
Amie Wilkinson
5:30pm|Remote Access Only

In 1978, Charles Conley classified all continuous dynamical systems. His theorem, dubbed the "fundamental theorem of dynamical systems" states that the orbits of any continuous map on a compact metric space fall into two classes: gradient-like and...

Neural SDEs: Deep Generative Models in the Diffusion Limit
Maxim Raginsky
12:00pm|Remote Access Only - see link below

In deep generative models, the latent variable is generated by a time-inhomogeneous Markov chain, where at each time step we pass the current state through a parametric nonlinear map, such as a feedforward neural net, and add a small independent...

Square function estimate for the cone in R^3
11:00am|Remote Access via Zoom videoconferencing (link below)

We prove a sharp square function estimate for the cone in R^3 and consequently the local smoothing conjecture for the wave equation in 2+1 dimensions. The proof uses induction on scales and an incidence estimate for points and tubes. This is joint...

The Non-Stochastic Control Problem
Elad Hazan
11:00am|https://theias.zoom.us/j/360043913

Linear dynamical systems are a continuous subclass of reinforcement learning models that are widely used in robotics, finance, engineering, and meteorology. Classical control, since the work of Kalman, has focused on dynamics with Gaussian i.i.d...

Reflections on Cylindrical Contact Homology
9:00am|https://princeton.zoom.us/j/745635914

This talk beings with a light introduction, including some historical anecdotes to motivate the development of this Floer theoretic machinery for contact manifolds some 25 years ago. I will discuss joint work with Hutchings which constructs...

MathZero, The Classification Problem, and Set-Theoretic Type Theory
David McAllester
3:00pm|Remote Access Only - see link below

AlphaZero learns to play go, chess and shogi at a superhuman level through self play given only the rules of the game. This raises the question of whether a similar thing could be done for mathematics --- a MathZero. MathZero would require a formal...

A geometric view on Iwasawa theory
Mladen Dimitrov
2:30pm|https://theias.zoom.us/j/959183254

We will investigate the geometry of the p-adic eigencurve at classical points where the Galois representation is locally trivial at p, and will give applications to Iwasawa and Hida theories.
