چکیده
|
In this manuscript, we investigate and study some cohomological properties of banach algebras. let a be a banach algebra with a bounded left approximate identity, and let b be a banach a − bimodule. we show that if ab∗∗ and b ∗∗a are subset of b, then h1 (a, b(2n+1)) = 0 for all n ≥ 0, whenever h1 (a, b∗ ) = 0.
