DESCRIPTION:Speaker: Peter Fiebig\nhosted by Tamas Hausel\nAbstract: To a f
 ixed root system one can associate various representation theories. Among 
 the more challenging are the representations of algebraic groups over a gr
 ound field of positive characteristic (the modular case)\, and of quantum 
 groups at a root of unity (the quantum case). Lusztig and Lusztig-Williams
 on conjectured the existence of infinitely many generations of representat
 ion theories\, the quantum case being the first generation\, and the modul
 ar case being the limit at infinity (for big enough prime characteristics)
 . For a fixed root system we provide a framework that includes both the mo
 dular and the quantum case\, and that allows to define infinitely many app
 roximations in between. These approximations  might serve as a candidate 
 for the Lusztig-Williamson generations.
