PBW and toric degenerations

E. B. Feigin



Abstract: We will describe the PBW degeneration of the irreducible representations of simple Lie algebras and of the corresponding flag varieties.
We will also explain how to degenerate the representations and flag varieties further to get toric structures. The connection with monomial bases will be clarified.
