Generalized Ricci Curvature Bounds for Three Dimensional Contact
Subriemannian Manifolds
Abstract: Measure contraction property (MCP) is one of the possible
generalizations of Ricci curvature bound to more general metric measure
spaces. However, the definition of MCP is not computable in general. In
this talk, I will discuss computable sufficient conditions for a three
dimensional contact subriemannian manifold to satisfy such property.
This is a joint work with Andrei Agrachev.

The Willmore Functional, a Perturbative Approach
Given a surface M immersed in a Riemannian manifold (M,g) of dimension
three, the Willmore functional I is defined as I(M)=\int_M H^2 dS where H
is the mean curvature and dS the area form given by the immersion.
The critical points of I are called Willmore surfaces and the aim of the
seminar is to study the existence of such surfaces.
The topic is classical and has many applications (general relativity,
biology, elasicity theory...); after an introduction about the employed
method (it is performed a finite dimentional reduction) we will study the
functional in a perturbative setting.
