本文提出了有限群块上同调环的概念，并利用与有限生成双模的有界复相关的对称代数的Hochschild上同调环之间的迁移映射研究了它的基本性质。
We develop the notion of a cohomology ring of blocks of finite groups and study its basic properties by means of transfer maps between the Hochschild cohomology rings of symmetric algebras associated with bounded complexes of finitely generated bimodules which are projective on either side.
