Abstract: In 1988, Gerhard Dziuk introduced the surface finite element method to solve the Poisson equation on arbitrary surfaces. Here, in this talk I will present recent work in which we derive a Cahn-Hilliard type equation on a given evolving surface. Questions of existence and uniqueness are addressed followed by a convergence result assuming regularity of solutions. If time allows I will then show how the method can be used to solve equations where the evolving of the surface is also an unknown. In particular, a natural time discretisation is used which gives better stability properties than other current methods.
