The nearby Lagrangian conjecture asks whether every closed exact Lagrangian in the cotangent bundle of a closed manifold is Hamiltonian isotopic to the zero section. Although relatively few results on this conjecture are known, some progress has...

Last year there were two sensational and independent breakthroughs on the Chowla cosine problem, each giving polynomial bounds for the first time. One by Bedert who used a very clever, but more “direct” Fourier argument. On the other hand, the other...

Abstract: Pulsar Timing Arrays (PTAs) are galaxy-sized gravitational-wave detectors built from the extraordinarily stable rotation of millisecond pulsars, designed to observe and understand the gravitational-wave universe at nanohertz frequencies...

I will discuss the interplay between rigidity and flexibility in symplectic dynamics, a topic that has fascinated me for much of my adult life.   I understand the situation in low-dimensions much better, and this will be the focus of my talk, but I...

Fundamental Local Equivalence of Gaitsgory and Lurie is an instance of quantum local geometric Langlands correspondence. It asserts an equivalence between the affine category $O$ and the category of twisted Whittaker $D$-modules on the affine flag...
