Derivations into annihilators of the ideals of Banach algebras

Blog Article

In this article, following jolly joes grape candy Gorgi and Yazdanpanah, we define two new concepts of the ideal amenability for a Banach algebra A.We compare these notions with J-weak amenability and ideal amenability, where J is a closed 75 corvette door panels two-sided ideal in A.We also study the hereditary properties of quotient ideal amenability for Banach algebras.Some examples show that the concepts of A/J-weak amenability and of J-weak amenability do not coincide for Banach algebras in general.
