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.
