SUMMARY:Balanced semisimple filtrations for tilting modules - Amit Hazi (U
 niversity of Cambridge)

DESCRIPTION:Tilting modules form an important class of finite-dimensional 
 representations for reductive groups in positive characteristic. We know v
 ery little about the structure of such modules in general\, including thei
 r characters and especially their Loewy series. In this talk I'll show how
  Soergel's tilting character formula for quantum tilting modules leads to 
 a remarkably straightforward algorithm for calculating tilting characters 
 by finding a particularly nice Loewy series called a balanced semisimple f
 iltration.
