Mariel Saez (Pontificia Universidad Catolica, Chile) will speak in the geometry seminar on Tuesday 26 February, at 2pm in the Salle de Profs. Mariel’s title is *On the uniqueness of graphical mean curvature flow* and her abstract is below.

In this talk I will discuss recent work with P. Daskalopoulos on sufficient conditions to prove uniqueness of complete graphs evolving by mean curvature flow. It is interesting to remark that the behaviour of solutions to mean curvature flow differs from the heat equation, where non-uniqueness may occur even for smooth initial conditions if the behaviour at infinity is not prescribed for all times.
