All day 

9am 
02/03/2023  9:30am A relaxedpace seminar on impromptu subjects related to the interests of the audience. Everyone is welcome. The subjects are geometry, probability, combinatorics, dynamics, and more! Location:
LOM 215

2pm 
02/03/2023  2:00pm In this talk, we will discuss some solutions of the mean curvature flow (MCF) of surfaces in the 3sphere. We will recall a generalized notion of MCF introduced by Brakke in the 70s, as well as its regularization by a parabolic partial differential equation arising in the theory of phase transitions. We will talk about some existence problems for this parabolic equation, and use them to construct MCFs that join minimal surfaces of low area in the 3sphere, and some recent progress on the spaces of MCFs using MorseBott theory. This is joint work with Pedro Gaspar (Pontificia Universidad Católica de Chile). Location:
