Banach spaces with few operators and multiplier results

open access: yes, 1997
The construction of a non-separable reflexive Banach space on which every operator is the sum of a scalar multiple of the identity operator and an operator of separable range is presented. Using a result of Rao, a sufficient condition is given for Banach

Additive Functional Inequalities in Banach Modules

open access: yesJournal of Inequalities and Applications, 2008
We investigate the following functional inequality in Banach modules over a -algebra and prove the generalized Hyers-Ulam stability of linear mappings in Banach modules over a -algebra in the spirit of the Th. M. Rassias stability approach. Moreover,

Norm decreasing algebra isomorphism of Banach algebras

open access: yes, 1976
In questa nota dimostriamo che se T è un'algebra-isomorfismo a norma decrescente di un'algebra di Banach $A_{1}$su un'algebra di Banach $A_{2},$ $(A_{1,}i=1,2$ essendo un $B^{*},$ $B(X),$$B^{\#}$), allora T è un'isometria.In this paper, we show that ...

Amenability Properties of Banach Algebra of Banach Algebra-Valued Continuous Functions

open access: yes, 2014
In this thesis we discuss amenability properties of the Banach algebra-valued continuous functions on a compact Hausdorff space X. Let A be a Banach algebra.
