Operators preserving ideals in C*-algebras

V. Shul'Man (1994)

Studia Mathematica

Similarity:

The aim of this paper is to prove that derivations of a C*-algebra A can be characterized in the space of all linear continuous operators T : A → A by the conditions T(1) = 0, T(L∩R) ⊂ L + R for any closed left ideal L and right ideal R. As a corollary we get an extension of the result of Kadison [5] on local derivations in W*-algebras. Stronger results of this kind are proved under some additional conditions on the cohomologies of A.

Conservative algebras and superalgebras: a survey

Communications in Mathematics

Similarity:

We give a survey of results obtained on the class of conservative algebras and superalgebras, as well as on their important subvarieties, such as terminal algebras.

On local derivations in the Kadison sense

Andrzej Nowicki (2001)

Colloquium Mathematicae

Similarity:

Let k be a field. We prove that any polynomial ring over k is a Kadison algebra if and only if k is infinite. Moreover, we present some new examples of Kadison algebras and examples of algebras which are not Kadison algebras.
