DESCRIPTION:Title: <a href="https://researchseminars.org/talk/FGV/4/">Pica
 rd groups for blocks with normal defect groups</a>\nby Claudio Marchi (Uni
 versity of Manchester (UK)) as part of Finite Groups in Valencia\n\n\nAbst
 ract\nLet $G$ be a finite group\, $B$ a $p$-block of $OG$\, $O$ a complete
  DVR. The Picard group of $B$ is the group of auto-Morita equivalences of 
 $B$ and it revealed itself to be a useful tool\, for example for dealing w
 ith Donovan conjecture. However\, it is also interesting in its own right\
 , since it has the structure of a finite group\, when $O$ has char 0.\n\nI
 n this talk we will give an introduction to Picard groups for blocks and t
 hen present joint work with Livesey on blocks with normal defect groups\, 
 providing evidence to a conjecture on basic Morita equivalences.\n
