DESCRIPTION:Title: <a href="https://researchseminars.org/talk/CIRGET/44/">
 Constant curvature conical metrics</a>\nby Xuwen Zhu (Northeastern Univers
 ity) as part of CRM - Séminaire du CIRGET / Géométrie et Topologie\n\n\
 nAbstract\nThe problem of finding and classifying constant curvature metri
 cs with conical singularities has a long history bringing together several
  different areas of mathematics. This talk will focus on the particularly 
 difficult spherical case where many new phenomena appear. When some of the
  cone angles are bigger than $2\\pi$\, uniqueness fails and existence is n
 ot guaranteed\; smooth deformation is not always possible and the moduli s
 pace is expected to have singular strata. I will give a survey of several 
 recent results regarding this singular uniformization problem\, connecting
  microlocal techniques with complex analysis and synthetic geometry. Based
  on joint works with Rafe Mazzeo\, Bin Xu\, and Mikhail Karpukhin.\n
