Linear operators are at the core of many of the most basic algorithms for signal and image processing. Matlab's high-level, matrix-based language allows us to express naturally many of the underlying matrixoperations---e.g. computation of matrix...

A basic question in probabilistic potential theory is the following: Consider a random proper subset K of R^d, for what nonrandom sets A is P{K intersect A not equal 0}? In this lecture we will give some abstract results when K is the range of a...

I will first describe a result on the uniqueness of invariant distributions for a certain process of coagulation and fragmentation. This result was firstproved by Diaconis, Mayer-Wolf, Zeitouni and Zerner (2004) using representation theory, but...

Nonlinear dynamical systems are prevalent in systems biology, where they are often used to represent a biological system. Its dynamical behaviour is often impossible to understand by intuition alone without such mathematical models. Ideas and methods...

Conjecture: For any map from a closed 4-manifold E to a circle whose homotopy fiber has the homotopy type of a 3-manifold, there exists a fiber bundle over the circle with total space a 4-manifold homotopy equivalent to E. Theorem (joint with Shmuel...

Suppose that H is an algebraic group which is defined over a field k, and let L be the algebraic closure of k. The canonical stalk for the etale topology on k induces a simplicial set map from the classifying space B(H-tors) of the groupoid of H...

Cocycle categories give a simple, flexible way to describe morphisms in a homotopy category, provided that the underlying model structure is sufficiently well behaved. "Well behaved" model structures include simplicial sets, spectra, simplicial...
