Tuesday, July 9th Phillipo Lappicy (Universidad Complutense de Madrid, Spain) An energy formula for fully nonlinear degenerate parabolic equations in one spatial dimension
Energy (or Lyapunov) functions are used to prove stability of equilibria, or to indicate a gradient-like structure of a dynamical system. Matano constructed a Lyapunov function for quasilinear non-degenerate parabolic equations. We modify Matano's method to construct an energy formula for fully nonlinear degenerate parabolic equations. We provide several examples of formulae, and in particular, a new energy candidate for the porous medium equation. This is a joint work with E. Beatriz.
