AbstractWe study some natural representations of current Lie algebras $g\otimes \Bbbk[t]$, called Weyl modules. They are natural analogues of irreducible representations of simple Lie algebras. There are several current analogues of classical theorems about Lie algebras where these modules «play role» of irreducible modules. In my talk I will explain analogues of duality theorems, namely Peter-...
AbstractLusztig has introduced semisimple perverse sheaves for quivers and the induction and restriction functors to categorify the positive part of the quantum groups and provoided the existence of the canonical basis. Even though one can use an algebraic construction to obtain the canonical basis of irreducible integrable highest weight modules, how to realize the integrable highest weight mo...
