Computer Science/Discrete Mathematics Seminar II

A Unified Approach to Discrepancy Minimization
Nikhil Bansal
10:30am|Simonyi Hall 101 and Remote Access

Discrepancy theory provides a powerful approach to improve upon the bounds obtained by a basic application of the probabilistic method. In recent years, several algorithmic approaches have been developed for various classical results in the area. In...

A Stacky Perspective on P-adic Non-abelian Hodge Theory
Arthur-Cesar Le Bras
4:30pm|Rubenstein Commons | Meeting Room 5

P-adic non abelian Hodge theory, also known as the p-adic Simpson correspondence, aims at describing p-adic local systems on a smooth rigid analytic variety in terms of Higgs bundles. I will explain in this talk why the « Hodge-Tate stacks »...

On Lagrangian Quasi-Cobordisms
Angela Wu
4:00pm|Simonyi 101 and Remote Access

A Lagrangian cobordism between Legendrian knots is an important notion in symplectic geometry. Many questions, including basic structural questions about these surfaces are yet unanswered. For instance, while it is known that these cobordisms form a...

Approximating Iterated Multiplication of Stochastic Matrices in Small Space
Dean Doron
11:15am|Simonyi 101 and Remote Access

Matrix powering, and more generally iterated matrix multiplication, is a fundamental linear algebraic primitive with myriad applications in computer science. Of particular interest is the problem’s space  complexity as it constitutes the main route...

Special Number Theory Afternoon

Murmurations of Arithmetic L-functions
Andrew Sutherland
4:00pm|Simonyi 101 and Remote Access

While conducting a series of number-theoretic machine learning experiments, He, Lee, Oliver, and Pozdnyakov noticed a curious oscillation in the averages of Frobenius traces of elliptic curves over Q.  If one computes the average value of a_p(E) for...

Special Number Theory Afternoon

Counting Irreducible Integral Polynomials with Roots Approximating Configuration of Points
2:30pm|Simonyi 101 and Remote Access

Suppose that $\Sigma \subset \mathbb{C}$ is compact and symmetric about the real axis and is a finite union of rectangles and real intervals with transfinite diameter $d_{\Sigma}>1$. Suppose that $\mu$ is a $H$ older arithmetic probability...

Brayan Ferreira (Instituto de Matemática Pura e Aplicada): 

Gromov Width of Disk Cotangent Bundles of Spheres of Revolution: The question of whether a Symplectic manifold embeds into another is central in Symplectic topology. Since Gromov...

Root Number Correlation Bias of Fourier Coefficients of Modular Forms
Nina Zubrilina
4:30pm|Simonyi Hall 101 and Remote Access

In a recent machine learning based study, He, Lee, Oliver, and Pozdnyakov observed a striking oscillating pattern in the average value of the P-th Frobenius trace of elliptic curves of prescribed rank and conductor in an interval range. Sutherland...
