Abstract

The example of invasion fronts - The approach based on Hamilton-Jacobi equations - Accelerating fronts - The tail problem

When used for biology and medicine, PDEs have to be used with care. Even though some are very classical, as front propagation for invading species, they are always questioned by comparison to observations or experiments. This course aims at showing some examples of free boundary problems motivated by biology and medicine, to concentrate on weak solutions, and to discuss their limitations and the need for further developments.
