DESCRIPTION:Speakers: Luozi Shi (Universität Münster)\n\nCovering groups
  are topological central extensions of G(F) by a finite abelian group\, w
 here F is a finite extension of Q_p and G is a reductive group over F. Wei
 ssman observed that the local Langlands correspondence for covering groups
  fails to be surjective in general. Our result shows that by considering c
 overs of all extended pure inner forms of G\, the surjectivity issue can b
 e resolved in the case of covering tori.\nIn the first part of the talk I 
 will present Brylinski-Deligne’s construction ofcovering groups\, explai
 n the notion of Weissman’s obstruction for surjectivity and the statemen
 t of the main theorem. In the second half of the talk\, I will discuss the
  construction of covers of extended pure inner forms using the language of
  étale metaplectic covers and the proof strategy. This talk is based on j
 oint work with Yifei Zhao.\n \n\nhttps://math-events.uni-bonn.de/event/12
