DESCRIPTION:Title: <a href="https://researchseminars.org/talk/BRAG/62/">Va
 nishing of Ext modules and characterizations of smoothness in algebraic va
 rieties</a>\nby Cleto B. Miranda-Neto (UFPB) as part of Brazilian algebrai
 c geometry seminar\n\n\nAbstract\nIn this talk\, after presenting some hom
 ological results which establish freeness criteria for modules\, I will di
 scuss how the vanishing of suitable Ext modules can be translated in terms
  of smoothness of a complex algebraic variety at a given point. Special at
 tention will be given\, e.g.\, to complete intersections and rational surf
 ace singularities.\n
