The Benjamin-Ono equation is a model for several physical phenomena, including gravity-driven internal waves in certain density-stratified fluids. It has the features of being a nonlocal equation (the dispersion term involves the Hilbert transform of...

The hp-adaptive finite elements combine elements of varying size h and polynomial order p to deliver approximation properties superior to any other discretization methods. The best approximation error converges exponentially fast to zero as a...

Abstract: This talk is based on a joint work with St\'ephane Kirsch. Pulsating traveling fronts are solutions of heterogeneous reaction-advection-diffusion equations that model some population dynamics. Fixing a unitary direction $e$, it is a well...

We give a model for the moduli space of Riemann surfaces with one or more boundary curves using harmonic functions and canonical tesselations. The resulting simplicial complex is homeomorphic to a flat vector bundle over the moduli space.

The simplest models of population genetics, useful as they are in analyzing data, often have obvious shortcomings. Such models might ignore the effects of natural selection, mutation, or, as we will be concerned with in this talk, geography and...

This talk presents some coherent though incomplete conjectures for the emergence, replication and abundance of some chemical structures found in each prokaryote, with special emphasis on the trines and the rRNA filaments that constitute a large part...

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...
