Title: | Relation between Hochschild homology and cohomology for Gorenstein rings | Authors: | VAN DEN BERGH, Michel | Issue Date: | 1998 | Publisher: | AMER MATHEMATICAL SOC | Source: | PROCEEDINGS OF THE AMERICAN MATHEMATICAL SOCIETY, 126(5). p. 1345-1348 | Abstract: | Let "HH" stand for Hochschild (co)homology. In this note we show that for many rings A there exists d is an element of N such that for an arbitrary A-bimodule N we have HHi(N) = HHd-z(N). Such a result may be viewed as an analog of Poincare duality. Combining this equality with a computation of Soergel allows one to compute the Hochschild homology of a regular minimal primitive quotient of an enveloping algebra of a semisimple Lie algebra, answering a question of Polo. | Notes: | Limburgs Univ Ctr, Dept WN1, B-3590 Diepenbeek, Belgium.Van den Bergh, M, Limburgs Univ Ctr, Dept WN1, Univ Campus, B-3590 Diepenbeek, Belgium. | Keywords: | Hochschild homology; Gorenstein rings | Document URI: | http://hdl.handle.net/1942/3238 | ISI #: | 000073199700012 | Type: | Journal Contribution | Validations: | ecoom 1999 |
