Additive Maps Preserving Local Spectrum

Integral Equations and Operator Theory, 2005
Let X be a complex Banach space, and let \(\mathcal{L}(X)\) be the space of bounded operators on X. Given \(T \in \mathcal{L}(X)\) and x ∈ X, denote by σT (x) the local spectrum of T at x.

Intuitionistic Fuzzy Approximately Additive Mappings

2011
In this paper, we investigate the generalized Hyers–Ulam stability and the intuitionistic fuzzy continuity of the generalized additive functional equation $$\begin{array}{rcl} & & {2}^{n-1}\;{a}_{ 1}f({x}_{1}) = f\bigg{(}\sum\limits_{i=1}^{n}{a}_{ i}{x}_{i}\bigg{)} \\ & & \quad +\sum\limits_{k=2}^{n}\ \sum\limits_{{i}_{1}=2}^{k}\ \sum\limits_{{i}_ ...

Almost Approximately Additive Mappings

1983
Answering a question of L. Reich, we here present two results about the behavior of functions satisfying the approximate additivity inequality almost everywhere with respect to an axiomatically given family of “small” (“negligible”) sets.

Approximate norm‐additive maps on Banach spaces

Bulletin of the London Mathematical Society
AbstractLet be two Banach spaces, be an ‐norm‐additive map for some , that is, In this paper, we prove that if is surjective with , then there exists a linear surjective isometry such that The estimate is sharp. We also approximate standard surjective ‐norm‐additive maps between the positive cones of continuous function spaces by linear isometries
