DESCRIPTION:Title: <a href="https://researchseminars.org/talk/CIRGET/90/">
 Hyperkähler metrics via deformation theory</a>\nby Maxence Mayrand (Sherb
 rooke University) as part of CRM - Séminaire du CIRGET / Géométrie et T
 opologie\n\nLecture held in PK-5115.\n\nAbstract\nHyperkähler structures 
 are special holonomy metrics with a particularly rich geometry. I will dis
 cuss methods for constructing such metrics\, and the weaker notion of hype
 rcomplex structures\, using the theory of deformation of complex structure
 s. As a consequence\, we obtain new hyperkähler metrics on certain Lie gr
 oupoids\, namely\, integrations of holomorphic Poisson surfaces\, by using
  results on the deformation theory of such surfaces.\n
