一类典型余模代数的等变分解

Equivariant Resolutions for a Class of Model Comodule Algebras

本文给出了非退化双线性型量子自同构群的一类典型余模代数的等变分解,由此得知此类余模代数满足Hochschild同调和上同调间的Poincaré对偶.

This paper gives equivariant resolutions for a class of model comodule algebras of quantum automorphisrn groups of non-degenerate bilinear forms. Consequently, such comodule algebras satisfies the Poincare duality between Hochschild homology and cohomology.
