Double dimers on planar hyperbolic graphs, via circle packings

May 7, 2025

MATH 105

I will present some new results about the double dimer model on hyperbolic graphs. We prove that there are no bi-infinite paths in the double dimer model on such graphs.

A key insight is the role circle packing plays for this model. First: we prove that on such graphs, the weak limit of... Read more

Mathematical models to untangle infectious disease eco-evolutionary dynamics

May 7, 2025

MATH 100

Infectious diseases are complex systems across many scales. In this talk, I will use mathematical models to investigate a range of questions in infectious disease eco-evolutionary dynamics. I will begin by modelling the transition from pathogen emergence to endemicity, landscapes of immunity,... Read more

Pseudo Matching To Identify Layers in Solid Electrolytes

May 7, 2025

MATH 225

We present a continuum model of charge transfer in a solid electrolyte which has a logarithmic singularity owing to a filling and emptying process. We use an auxiliary variable to regularize and simulate the model. We show that an electrically neutral bulk layer is present along with space... Read more

Hensel's lemma for the norm principle for groups of type $D_n$

May 7, 2025

MATH 204

Let $G$ be a linear algebraic group defined over a field $K$. The Norm Principle for $G$ examines how the base change of $G$ to finite separable field extensions of $K$ behaves with respect to the norm map of the field extensions. It remains an open question whether the norm principle holds for... Read more

Building mathematical model of cell leading edge from multiplex data

May 7, 2025

MATX 1100

Many cells in our body migrate - 'good' examples are wound healing, embryogenesis and immune response; 'bad' example is metastasis. Migration starts with leading edge protrusion, which is enabled by branching growth of actin network and resisted by membrane tension. Two main molecular players in... Read more

Combinatorial applications of the Lévy–Khintchine formula

May 7, 2025

MATH 105

The Lévy–Khintchine formula relates an infinitely divisible probability measure to its Lévy measure, which controls the jumps of the associated Lévy process. If the Lévy measure is well behaved then the two measures are asymptotically equivalent (the one big jump principle). Using this framework... Read more

An immersed boundary model for fluid-structure interaction in the cochlea

May 7, 2025

MATH 225

The mammalian ear has a remarkable ability to distinguish sounds that differ only slightly in frequency, while at the same time amplifying these signals so that they can be converted into neural impulses. This phenomenon is commonly attributed to some form of mechanical resonance within the... Read more

Khovanov homology and Conway mutation

May 7, 2025

MATH 104

What has homological mirror symmetry ever done for you? I will give my personal answer to that question and discuss joint work in progress with Liam Watson and Artem Kotelskiy concerning the behaviour of Khovanov homology under Conway mutation.

Claudius was a postdoctoral fellow at... Read more

MATH 104

This will be an introduction to the single- and double-dimer models, which arise in many places in mathematics (including in equivariant localization calculations of enumerative invariants). Read more
