UW Combinatorics and Geometry Seminar: Daoji Huang
October 9, 2024
University of Washington
Influential work of Hodge from the 1940s led the way in using Gröbner bases to combinatorially study the Grassmannian. In this talk, we will follow Hodge's approach in order to investigate certain subvarieties called positroid varieties. Positroid...

In the colored asymmetric simple exclusion process, one places a particle of "color" −k at each integer site k∈ℤ. Particles attempt to swap places with an adjacent particle: at rate q∈[0,1) if they are initially ordered (e.g., 1 then 2) and at rate 1...

The Moran process models the evolutionary dynamics between two competing types in a population, traditionally assuming a fixed population size. We investigate an extension to this process which adds ecological aspects through variable population...

In this talk, I will discuss recent progress on the directed Oberwolfach problem. A directed variant of the famous Oberwolfach problem, the directed Oberwolfach problem considers the fol- lowing scenario. Given m people and t round tables of size m1...

The chromatic polynomial of a graph G counts the number of proper k-colorings of G. In 1995, Stanley extended this concept to define the chromatic symmetric function of a graph, which lives in the ring Sym of all symmetric functions. Building on this...

L-functions in Analytic Number Theory: Christine K. Chang
October 8, 2024
Online
We will present a matching upper and lower bound for the right tail probability of the maximum of a random model of the Riemann zeta function over short intervals. In particular, we show that the right tail interpolates between that of log-correlated...

Lethbridge Number Theory and Combinatorics Seminar: Emily Quesada Herrera
October 7, 2024
University of Lethbridge
In 1973, assuming the Riemann hypothesis (RH), Montgomery studied the vertical distribution of zeta zeros, and conjectured that they behave like the eigenvalues of some random matrices. We will discuss some models for zeta zeros � starting from the...

UBC Algebra and Algebraic Geometry: Sebastian Gant
October 7, 2024
University of British Columbia
We study the question of when a generic stably free module splits off a free summand of a given rank. This question has the following geometric interpretation due to M. Raynaud. Let V(r,n) denote the Stiefel variety GL(n)/GL(n-r) over a field k...

UBC Math Department Colloquium: Sebastien Picard
October 4, 2024
University of British Columbia
It was proposed in the works of Reid in the mathematics literature and Candelas-Green-Hubsch in the string theory literature to connect Calabi-Yau threefolds with different topologies by a process which degenerates 2-cycles and introduces new 3...

UAlberta Math Biology Seminar: Bo Zhang
October 4, 2024
University of Alberta
Understanding mechanisms of coexistence is a central topic in ecology. Mathematical analysis of models of competition between two identical species moving at different rates of symmetric diffusion in heterogeneous environments show that the slower...
