Computer Science/Discrete Mathematics Seminar I

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...

Three 20-min Research Talks
9:15am|Remote Access

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...

What is...?

What is a D-module?
Lizzie Pratt
1:00pm|Simonyi 101 and Remote Access

In this talk, we will discuss the computation of motivic stable homotopy groups and their applications in classical computations. Specifically, we will discuss an example of complex motivic applications in classical theory, the Adams spectral...

Algebraic Aspects of Normality and Determinism.
Tomasz Downarowicz
10:30am|Simonyi 101 and Remote Access

In 1976, Gérard Rauzy proved a characterization of deterministic numbers: y is deterministic iff for any normal number x, x+y is also normal. During my lecture I willdiscuss  how normal and deterministic numbers behave under arithmetic operations. ...

Polynomial Patterns in Finite Fields: a Dynamical Point of View
2:00pm|Simonyi 101 and Remote Access


In its dynamical formulation, the Furstenberg—Sárközy theorem states that for any invertible measure-preserving system $(X, \mu, T)$, any set $A \subseteq X$ with $\mu(A) > 0$, and any integer polynomial $P$ with $P(0) = 0$,
$$c(A) = \lim_{N-M \to...
