Category O for Takiff sl_2


الملخص بالإنكليزية

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