Fifteen papers from the three workshops test perverse coherent sheaves on the nilpotent cone, prove the Kac-Wakimoto atypicality conject rue for a Lie superalgebra, locate non-trivial cohomology classes for finite groups of Lie type II, and derive a semi-simple series for q-Weyl and q-Sprecht modules. Survey articles describe current efforts to classify endotrivial modules over the group algebras of finite groups, recent developments in the theory of affine q-Schur algebras, and Frobenius twists in the representation theory of the symmetric group.
