The Hilbert--Einstein functional and the Sasaki-Futaki invariant - Eveline Legendre [2016]
Abstract: I will show how the Hilbert--Einstein functional detects the Reeb vector fields having a vanishing transversal Futaki invariant and so that it is an obstruction to the existence of constant scalar curvature Sasaki metrics. I will also discuss the relation of this functional with

F. Baudoin - Uniform sub-Laplacian comparison theorems on Sasakian manifolds
We will discuss sharp estimates for the sub-Laplacian of a family of distances converging to the sub-Riemannian one. We will deduce results for the sub-Riemannian distance. Uniform measure contraction properties will also be discussed. This is joint work with Erlend Grong, Kazumasa Kuwada

Sasaki geometry and positive curvature - Song Sun [2012]
Abstract: We classify simply connected compact Sasaki manifolds with positive transverse bisectional curvature. In particular, the moduli space of all such manifolds can be contracted to a point—the standard round sphere. This provides an alternative proof of the Mori-Siu-Yau theorem on Fr

The notion of a Poisson manifold originated in mathematical physics, where it is used to describe the equations of motion of classical mechanical systems, but it is nowadays connected with many different parts of mathematics. A key feature of any Poisson manifold is that it carries a cano
