Infinite and bi-infinite incipient clusters in high dimension

September 10, 2025

ESB 2012

The incipient infinite cluster is a critical percolation cluster that is conditioned on being infinitely large. Even though the condition has probability zero, Kesten demonstrated the first such construction for critical two-dimensional percolation in 1986 through a suitable limiting scheme.... Read more

Math-Bio: The Rainbow and the Brain

September 10, 2025

ESB 4133

The rainbow and the brain have in common that frequencies are produced. In both cases there is a function of frequency, f, called the power spectral density (PSD). In both cases invasive investigation spoils the investigated object. This talk will describe using noninvasive... Read more

Descendent transformations in Donaldson-Thomas wall-crossings

September 8, 2025

MATH 126

In recent work with Felix Thimm and Nick Kuhn, we proved a Joyce-style "universal" wall-crossing formula for certain equivariant moduli problems of 3-Calabi-Yau type, including Donaldson-Thomas theory. An immediate and productive question is how tautological classes like descendents transform... Read more

Analyticity of Solutions to Fractional Partial Differential Equations

August 26, 2025

MATH 105

We will explore a classic topic in the realm of partial differential equations (PDEs) within a contemporary context: the analyticity of solutions to elliptic equations. While initial results for classical elliptic PDEs were established by Bernstein in 1904, the landscape for fractional and non-... Read more

Niven & Hugh Morris Lecture | From malaria to ChatGPT: the birth and strange life of the random walk

May 27, 2025

GEOG 100

Between 1905 and 1910 the idea of the random walk, now a major topic in applied math, was invented simultaneously and independently by multiple people in multiple countries for completely different purposes, from mosquito control to physics to finance to winning a theological argument (really!)...

Smyth's conjecture and a non-deterministic Hasse principle

May 26, 2025

ESB 4133

The matrix ( 3 -3 4 -4 5 -5 0 0 4 -4 -3 3 0 0 5 -5 -5 5 0 0 -3 3 -4 4 ) has an interesting property. Can you see what it is?

In case this puzzle is not enough information about the talk: I will explain how to prove a conjecture of Smyth from 1986 about linear relations between Galois... Read more

Structure, expansion and probability in vertex-transitive graphs

May 19, 2025

MATX 1101

Celebrated theorems of Gromov, Trofimov and Coulhon-Saloff-Coste combine to give a remarkable dichotomy for vertex-transitive graphs: such graphs must either resemble highly structured Cayley graphs, or must exhibit "expansion" in a certain sense. This in turn has had a number of striking... Read more
