On the Cremona dimension of a finite p-group

November 17, 2025

The Cremona dimension of a finite group G is the minimal dimension of a rationally connected variety which admits a faithful action of G. In this talk, based on joint work with Giulio Bresciani and Angelo Vistoli, I will discuss new lower bounds on the Cremona dimension of a finite p-group. Read more

Motives of certain hyperplane sections of homogeneous varieties

November 10, 2025

MATH 126

Let G be a split reductive group. For X a projective G-homogeneous variety, there is a description of the decomposition of the Chow motive of X (Chernousov-Gille-Merkurjev, Brosnan). It is also known that these varieties satisfy the so-called Rost nilpotence principle. In classical cohomology... Read more

Supporting student growth: connecting students with mathematics

November 7, 2025

ESB 2012 and Zoom

In this talk, I will describe three projects designed to support students’ development as mathematical thinkers, with a focus on their engagement with mathematics. First, I will discuss the co-creation of ‘Student Perspective’ course materials for Math 220 (Mathematical Proof) that address... Read more

On the energy image density conjecture of Bouleau and Hirsch

November 5, 2025

We affirmatively resolve the energy image density conjecture of Bouleau and Hirsch (1986). This conjecture generalizes a foundational result in Malliavin calculus: the non-degeneracy of the Malliavin matrix of a random variable implies absolute continuity of its law. This property is a key step... Read more

The role of basement membrane mechanics in the form and function of tissues

November 5, 2025

Zoom

Epithelial tissues that line many of the body organs are often formed by a layer of living cells surrounded by the non-living basement membrane (BM). During development and in normal physiology, the organs and their lining epithelial tissues are exposed to different rates and extents of... Read more

Expansion coefficients of powers of Vandermonde determinants

November 4, 2025

ESB 4127 (PIMS)

Powers of Vandermonde determinants serve as model wave functions for the fractional quantum Hall effect. In this talk I will explain how one can realize the coefficients in the monomial basis as expectation values of operator products and how this captures the relevant features of those wave...

Algebraic fiberings of groups

October 31, 2025

ESB 2012 and Zoom

We say that a finitely generated group algebraically fibers if it admits a homomorphism onto the integers with finitely generated kernel. This is a group theoretic analogue of the manifold property of being a fibre bundle over a circle. In this talk, I will give an overview of this and related... Read more
