Derivations into annihilators of the ideals of Banach algebras

Blog Article

In this article, following Gorgi and Yazdanpanah, we define two new concepts animed blue lotion topical spray 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 two-sided ideal in A.We also beaker creatures series 1 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.
