Reflections on generating (disjunctive) cuts

We consider the problem of constructing generic supporting hyperplanes to be used within a (branch and) bound-and-cut algorithm.We review some of the properties that these hyperplanes should enjoy.It is generally admitted that they should cut a parasitic point generated Diacs during the process.We argue that the advantages of restricting supports t

Derivations into annihilators of the ideals of Banach algebras

In this article, following 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 Still Life Art is a closed two-sided ideal Cutlery in A.We also study the hereditary properties of quotient ideal amenability for Banach algebras
