Abstract Wave phenomena occur on an enormous range of scales, from the sub-quantum mechanical to the astrophysical. This talk will discuss the problem of free surface waves in water, which is a classical problem in mathematical hydrodynamics. We will...

A strongly regular graph srg(v,k,lambda,mu) is a graph with v vertices that is regular of valency k and that has the following properties: (1) For any two adjacent vertices x,y, there are exactly lambda vertices adjacent to both x and y. (2) For any...

Abstract: A strongly regular graph srg(v,k,lambda,mu) is a graph with v vertices that is regular of valency k and that has the following properties: (1) For any two adjacent vertices x,y, there are exactly lambda vertices adjacent to both x and y. (2...

As part of Smale's program for smooth dynamics, David Ruelle gave a definition of a Smale space as (roughly) a topological dynamical system which has a local product structure of contracting and expanding directions for the dynamics. A special case...

Abstract The electrophysiology in a cardiac cell can be modelled as a system of ordinary differential equations. The efficient solution of these systems is important because they must be solved many times as sub-problems of tissue- or organ-level...

Principal component analysis (PCA) is a widely used technique for data analysis and dimension reduction with numerous applications in science and engineering. However, the standard PCA suffers from the fact that the principal components (PCs) are...

Aim of the talk is to make a survey on some recent results concerning analysis over spaces with Ricci curvature bounded from below. I will show that the heat flow in such setting can be equivalently built either as gradient flow of the natural...

This talk is the second talk in a series of talks about Hochschild (co)homology and cyclic (co)homology

I will describe recent work on motivic DT invariants for 3-manifolds, which are expected to provide a refinement of Chern-Simons theory. The conclusion will be that these should be possible to define and work with, but there will be some interesting...
