Achievement of continuity of $(ϕ, ψ)$ -derivations without continuity

S. Hejazian, A. R. Janfada, M. Mirzavaziri +1

Suppose that $\calak$ is a $C^{*}$ -algebra acting on a Hilbert space $\calhk$, and that $ϕ, ψ$ are mappings from $\calak$ into $B(\calhk)$ which are not assumed to be necessarily lin…

A Kadison-Sakai Type Theorem

M. Mirzavaziri, M. S. Moslehian

The celebrated Kadison--Sakai theorem states that every derivation on a von Neumann algebra is inner. In this paper, we prove this theorem for ultraweakly continuous *-σ-derivation…
