DESCRIPTION:Magalie Benefice (Bordeaux)\n\nAbstract: Coupling is an inter
 esting method to obtain results in Probability\, Optimal transport but als
 o in Analysis and Geometry. In particular\, it is useful to study hypoelli
 ptic diffusions as it doesn't need the intervention of some geometric or a
 nalytic objects that are difficult to define. In this talk I will study co
 uplings of the subelliptic Brownian motion in subRiemannian manifolds. I w
 ill present the constructions of successful couplings on the Heisenberg gr
 oup\, $SU(2)$ and (under some hypothesis) on $SL(2\,\\mathbb{R})$. I will 
 also give some direct applications on the associated semi-group and on har
 monic functions.\n
