Backward Uniqueness results in Extrinsic Geometric Flow

May 7, 2025

MATH 202

In this talk we discuss two backward uniqueness theorems for extrinsic geometric flow of possibly non-compact hypersurfaces in general ambient complete Riemannian manifolds. These are applicable to a wide range of extrinsic geometric flow, including the mean curvature flow, inverse mean... Read more

Large-scale pattern formation for spikes in reaction-diffusion systems

May 7, 2025

MATH 225

Many reaction-diffusion systems exhibit patterns consisting of spikes (or spots), and numerous techniques have been developed over the years to study them. In the limit of many spikes, we develop a mean-field theory to describe an effective spike density. The resulting description consists of... Read more

Expanding soliton from metric cone

May 7, 2025

MATH 202

In this talk, we will discuss how Ricci flow smoothing can be used to produce expanding Ricci solitons coming out of a metric cone, when the curvature is non-negative. We will discuss how its relation to problem in Hamilton-Lott pinching conjecture. This is based on joint work with Chan and... Read more

Critical long-range percolation

May 7, 2025

MATH 105

It is conjectured that many models of statistical mechanics have a rich, fractal-like behaviour at and near their points of phase transition, with power-law scaling governed by critical exponents that are expected to depend on the dimension but not on the small-scale details of the model such as...

Blocking sets and plane curves over finite fields

May 7, 2025

MATH 204

Let Fq be a finite field of order q. A subset B of a projective plane over Fq is called a blocking set if every line defined over Fq intersects B. Given an algebraic plane curve C, under what conditions does the set of Fq-points on C form a blocking set? We show that curves of low degree do not... Read more

Environmental feedback can maintain cooperation in viruses

May 7, 2025

MATX 1100

The evolution and maintenance of cooperation is a fundamental problem in evolutionary biology. Because cooperative behaviors impose a cost, cooperators are vulnerable to exploitation by defectors that do not pay the cost to cooperate but still benefit from the cooperation of others. Viruses...

Organization of Plant Cortical Microtubules

May 7, 2025

MATX 1100

The self-organization of cortical microtubule arrays within plant cells is an emergent phenomenon with important consequences for the synthesis of the cell wall, cell shape, and subsequently the structure of plants. Mathematical modelling and experiments have elucidated the underlying processes... Read more
