DESCRIPTION:Speaker:  Micheal Livesey\n\nTitle: RoCK blocks for double co
 vers of symmetric groups\n\nAbstract: Broué's conjecture posits that a b
 lock with abelian defect group is derived equivalent to its Brauer corre
 spondent. A RoCK block is even Morita equivalent to its Brauer correspon
 dent. The existence of RoCK blocks is\, therefore\, fundamental to the s
 tudy of Broué's conjecture for many classes of blocks of finite groups. 
 In this talk we investigate RoCK blocks for double covers of symmetric g
 roups. The proof that we do indeed have a Morita equivalence very much m
 irrors that of the corresponding result for the symmetric group\, origin
 ally proved by Chuang-Kessar. However\, there are many interesting diffe
 rences that greatly complicate the situation and require several differe
 nt techniques to overcome.\n\n\nPlace: Frank Adams (this term the semina
