DESCRIPTION:Title: <a href="https://researchseminars.org/talk/CIRGET/96/">
 Minimal Euler Characteristics for Even-Dimensional Manifolds with Finite F
 undamental Group</a>\nby Alejandro Adem (University of British Columbia) a
 s part of CRM - Séminaire du CIRGET / Géométrie et Topologie\n\nLecture
  held in PK-5115.\n\nAbstract\nIn this talk we will discuss estimates for 
 the minimal Euler characteristic of even dimensional manifolds with a give
 n finite fundamental group and a highly connected universal cover. In part
 icular we strengthen the Hausmann-Weinberger invariants and extend them to
  higher dimensions. As an application we obtain new restrictions for non-a
 belian finite groups arising as fundamental groups of rational homology 4
 –spheres. This is joint work with Ian Hambleton.\n\nNote that we have 2 
 talks this week\, one at 10 am (E. Cliff)\, another one at 11 am (A. Adem)
