On minimal norms on
Madjid Mirzavaziri, Mohammad Sal Moslehian
In this note, we show that for each minimal norm on the algebra of all complex matrices, there exist norms and on ${\mathb…
Achievement of continuity of -derivations without continuity
S. Hejazian, A. R. Janfada, M. Mirzavaziri +1
Suppose that $\calak$ is a -algebra acting on a Hilbert space $\calhk$, and that are mappings from $\calak$ into $B(\calhk)$ which are not assumed to be necessarily lin…
A Fixed Point Approach to Stability of a Quadratic Equation
M. Mirzavaziri, M. S. Moslehian
Using the fixed point alternative theorem we establish the orthogonal stability of quadratic functional equation of Pexider type , where are m…
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…
Automatic Continuity of -Derivations on -Algebras
Madjid Mirzavaziri, Mohammad Sal Moslehian
Let be a -algebra acting on a Hilbert space , be a linear mapping and be a -derivation. Generalizing the celebrated theorem of Sakai, we…
-Derivations in Banach Algebras
M. Mirzavaziri, M. S. Moslehian
Introducing the notions of (inner) -derivation, (inner) -endomorphism and one-parameter group of -endomorphisms (-dynamics) on a Banach algebra, we correspond to each $…
