Derivations preserving quasinilpotent elements
J. Alaminos, M. Brešar, J. Extremera +2
We consider a Banach algebra with the property that, roughly speaking, sufficiently many irreducible representations of on nontrivial Banach spaces do not vanish on all squ…

Identifying derivations through the spectra of their values
M. Brešar, B. Magajna, Š. Špenko
We consider the relationship between derivations and of a Banach algebra that satisfy $\s(g(x)) \subseteq \s(d(x))$ for every , where $\s(\, . \,)$ stands for t…

A Note on Values of Noncommutative Polynomials
Matej Bresar, Igor Klep
We find a class of algebras A satisfying the following property: for every nontrivial noncommutative polynomial, the linear span of all its values in A equals A. This class include…
