On semi-infinite cohomology of finite dimensional algebras

Roman Bezrukavnikov

Published 2000-05-15, updated 2000-11-03Version 3

We show that semi-infinite cohomology of a finite dimensional graded algebra (satisfying some additional requirements) are a particular case of a general categorical construction. The motivating example is provided by small quantum groups at a root of unity.

Comments: 8 pages. Some expositional changes made; few remarks added, one of them concerning semi-infinite cohomology of small quantum groups
