The Min system in E.coli -- a group of three interacting proteins playing a role in cell division -- has attracted a lot of attention by modellers, some claiming it to be the 'measurement stick' in the rod-shaped bacterium. Different models have been...

We study the controllability of a shape changing body immersed in a perfect fluid. The shape changes are prescribed as functions of time and satisfy constraints ensuring that they are due to the work of body's internal forces only. The net locomotion...

Growth is involved in many fundamental biological processes such as morphogenesis, physiological regulation, or pathological disorders. It is, in general, a process of enormous complexity, involving genetic, biochemical, and physical components at...

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...
