Members' Colloquium

Simple Zeros of Modular Form L-Functions
Alexandre de Faveri
2:00pm|Simonyi Hall 101 and Remote Access - see Zoom link below

Zeros of L-functions have been extensively studied, due to their close connection to arithmetic problems. Despite several precise conjectures about their behavior, our unconditional understanding of them remains limited. In this talk we will discuss...

Computer Science/Discrete Mathematics Seminar I

Common Linear Patterns Are Rare
Nina Kamčev
11:15am|Simonyi 101 and Remote Access

Several classical results in Ramsey theory (including famous theorems of Schur, van der Waerden, Rado) deal with finding monochromatic linear patterns in two-colourings of the integers.  Our topic will be quantitative extensions of such results.  A...

Probability Seminar

Fractal properties, noise-sensitivity and chaos in models of random geometry.
Shirshendu Ganguly
11:15am|West Lecture Hall and Remote Access

Planar last passage percolation models are canonical examples of stochastic growth, polymers and random geometry in the Kardar-Parisi-Zhang universality class, where one considers oriented paths between points in a random environment accruing the...

Efficient Stability for the Weyl-Heisenberg Group
Thomas Vidick
11:00am|Simonyi Hall 101 and Remote Access - see Zoom link below

The question of stability of approximate group homomorphisms was first formulated by Ulam in the 1940s. One of the most famous results in this area is Kazhdan's 1982 result on stability of approximate unitary representations of an amenable group...

A Relative Calabi-Yau Structure for Legendrian Contact Homology
Georgios Dimitroglou Rizell
9:15am|Remote Access

The duality long exact sequence relates linearised Legendrian contact homology and cohomology and was originally constructed by Sabloff in the case of Legendrian knots. We show how the duality long exact sequence can be generalised to a relative...

Integrality of Theta Liftings to a Definite U(2)
Yu-Sheng Lee
4:30pm|Princeton University, Fine Hall 214

We discuss the integrality of theta liftings of anti-cyclotomic characters to a definite unitary group of two variables. This will allow us to construct a Hida family of the theta liftings and relate the congruence module of which to an anti...

Marston Morse Lectures

From Nonlocal Games to Undecidability
Thomas Vidick
11:00am|Simonyi Hall 101 and Remote Access - see Zoom link below

In this lecture I will present basic elements of the theory of nonlocal games from quantum information theory and give some examples. I will then introduce the idea of "compressing" the complexity of nonlocal games, and show how the right form of...
