چکیده
|
Let s be a (not necessarily commutative) clifford semigroup with idempotent set e. in this paper, we show that the first (second) hochschild cohomology group and the first (second) module cohomology group of semigroup algbera ℓ 1 (s) with coefficients in ℓ ∞(s) (and also ℓ 1 (s) (2n−1) for n ∈ n) are equal.
