Category O for Takiff sl(2)

• investigate various ways to define an analog of Bernstein-Gelfand-Gelfand category O for the nonsemisimple Takiff extension of the Lie algebra sl(2). We describe Gabriel quivers for blocks of these analogs of category O and prove the extension fullness of one of them in the category of all modules.
