Category O for Takiff sl_2

Representation Theory 2023-03-15 v2

Abstract

We investigate various ways to define an analogue of BGG category O\mathcal{O} for the non-semi-simple Takiff extension of the Lie algebra sl2\mathfrak{sl}_2. We describe Gabriel quivers for blocks of these analogues of category O\mathcal{O} and prove extension fullness of one of them in the category of all modules.
