Bicommutants and ranges of derivations

Bojan Magajna

Let $V$ be a vector space over a field $F$ , $V^{*}$ its dual space and $L (V)$ the algebra of all linear operators on $V$ . For an operator $a \in L (V)$ let $a *$ be its adjoint acting o…

Identifying derivations through the spectra of their values

M. Brešar, B. Magajna, Š. Špenko

We consider the relationship between derivations $d$ and $g$ of a Banach algebra $B$ that satisfy $\s(g(x)) \subseteq \s(d(x))$ for every $x \in B$ , where $\s(\, . \,)$ stands for t…
