摘要：
Koam and Pirashivili developed the equivariant version of Hochschild cohomology by mixing the standard chain complexes computing group with associative algebra cohomologies to obtain the bicomplex (C) over tilde (G)*(A, X). In this paper, we form a new bicomplex (sic)(G)* (A, X) by deleting the first column and the first row and reindexing. We show that (1)((sic)G) (A, X) classifies the singular extensions of oriented algebras.
