DESCRIPTION:Title: <a href="https://researchseminars.org/talk/CIRGET/136/"
 >Transversal slices in quasi-Poisson manifolds</a>\nby Ana Balibanu (Louis
 iana State Univ.) as part of CRM - Séminaire du CIRGET / Géométrie et T
 opologie\n\nLecture held in PK-5115.\n\nAbstract\nQuasi-Poisson manifolds 
 are multiplicative generalizations of ordinary Poisson manifolds in which 
 the Jacobi identity is twisted by the action of a group. We study a class 
 of transversal slices to this group action which are motivated by geometri
 c representation theory. We show that these transversal slices can be thou
 ght of as Hamiltonian reductions of the ambient quasi-Poisson structure\, 
 and we use this to construct examples of old and new Poisson structures in
  representation theory. This is joint work with Maxence Mayrand.\n
