Fine Hall 322

Please note double seminar on this date.  In this talk we are going to review some recent results concerning the evolution of a free boundary under Darcy's flow. This is known as the Muskat problem or the Hele-Shaw cell problem with gravity. In particular, we will present a new method based on the study of the bulk rather than the appropriate integral equation.
