New Algebraic Invariants of Legendrian Links
Lenhard Ng
9:15am|Remote Access

For the past 25 years, Legendrian contact homology has played a key role in contact topology. I'll discuss a package of new invariants for Legendrian knots and links that builds on Legendrian contact homology and is derived from rational symplectic...

Resolution of the Kohayakawa--Kreuter Conjecture
Raphael Steiner
10:30am|Simonyi Hall 101 and Remote Access

A graph $G$ is said to be Ramsey for a tuple of graphs ($H_1,...,H_r$) if every $r$-coloring of the edges of $G$ contains a monochromatic copy of $H_i$ in color $i$, for some $i$. A fundamental question at the intersection of Ramsey theory and the...

Computer Science/Discrete Mathematics Seminar I

Quantum Mechanics, Semidefinite Programming, and Graph Invariants
Matthew Hastings
11:00am|Simonyi 101 and Remote Access

The central problem of physics and quantum chemistry is to find the ground state energy of some physical system governed by quantum mechanics.  In mathematical terms, this means finding the lowest eigenvalue of some linear operator on a vector space...

Supersymmetric Approach to the Analysis of Random Band Matrices
2:30pm|Simonyi Hall 101 and Remote Access

We discuss an application of the SUSY approach to the analysis of spectral characteristics of hermitian and non hermitian random band matrices. In 1D case the obtained integral representations for correlation functions of characteristic polynomials...

Invariant Sets and Hyperbolic Periodic Orbits
Viktor Ginzburg
9:15am|Remote Access

The presence of hyperbolic periodic orbits or invariant sets often has an affect on the global behavior of a dynamical system. In this talk we discuss two theorems along the lines of this phenomenon, extending some properties of Hamiltonian...

Derived Hecke Action For Weight One Modular Forms Via Classicality
Gyujin Oh
3:30pm|Simonyi 101 and Remote Access

It is known that a p-adic family of modular forms does not necessarily specialize into a classical modular form at weight one, unlike the modular forms of weight 2 or higher. We will explain how this obstruction to classicality leads to a "derived"...

The Geometric Langlands Conjecture
Sam Raskin
3:30pm|Simonyi Hall 101 and Remote Access

I will describe the main ideas that go into the proof of the (unramified, global) geometric Langlands conjecture. All of this work is joint with Gaitsgory and some parts are joint with Arinkin, Beraldo, Chen, Faergeman, Lin, and Rozenblyum. I will...
