Mechanistic models of cell migration

April 15, 2026

ESB 4133

Cell migration plays a role in many contexts including cancer cell metastasis and wound healing. Better characterizing the process can help us slow down or speed up cells and improve related conditions. To this end, we developed two different models of cell migration across a flat substrate. The... Read more

Hypersurfaces passing through the Galois orbit of a point

April 13, 2026

MATH 104

Asgarli, Ghioca, and Reichstein recently proved that if $K$ is a field with $|K|>2$, then for any positive integers $d$ and $n$, and separable field extension $L/K$ with degree $m=\binom{n+d}{d}$, there exists a point $P\in \mathbb{P}^n(L)$ which does not lie on any degree $d$ hypersurface...

An introduction to the CP-process for Furstenberg's intersection conjecture

April 9, 2026

ESB 4133

For two multiplicatively independent positive integers p and q, Furstenberg (2019) conjectured that the transformations px mod 1 and qx mod1 are transverse. This means that the Hausdorff dimension of the intersection of two closed invariant sets is bounded by the sum of their Hausdorff... Read more

A comparison of Segal and Waldhausen K-theory

April 7, 2026

Higher algebraic K-theory is a powerful invariant which was originally defined for rings, but has since grown far beyond its initial scope to encompass increasingly rich and intricate settings. There are many different constructions of algebraic K-theory, reflecting the range of uses and... Read more

Generic curves non-coprime Catalans

April 6, 2026

MATH 104

Given a plane curve singularity with a parametrization (x(t),y(t)), one can define its compactified Jacobian as the moduli space of (x(t),y(t))-submodules in the ring of power series in t. Affine pavings of compactified Jacobians for various families of curves have been extensively studied... Read more

Mathematics for AI: What Algebraic Geometry Brings to the Table?

April 6, 2026

MATH 104

In this talk, I will give an overview of (neuro)algebraic geometry, an emerging field analogous to algebraic statistics that uses algebraic geometry to study the theory of deep learning. I will focus on feedforward neural networks. The universal approximation theorem tells us that, with... Read more

Embedding Theorems in Symbolic Dynamics

April 2, 2026

ESB 4133

This talk will focus on the embedding problem: given two subshifts, under what conditions can one be embeded into the other? We will start with the classical Krieger embedding theorem which give criteria for embedding a subshift into a mixing SFT. We then present our recent results on... Read more

Mixing times for exclusion processes with open boundaries

April 1, 2026

ESB 2012

In this talk, we consider the asymmetric simple exclusion process with open boundaries (open ASEP). We give an overview on recent results on mixing times for the open ASEP. In particular, we discuss mixing times for the open ASEP at the triple point. This talk is based on joint work with Patrik... Read more
