New additive results of *-DMP elements on Banach algebras
Ali Ghaffari, Fatemeh Zamiri, Marjan Sheibani
We present new additive results for DMP elements in a Banach algebra with involution. The necessary and sufficient conditions under which the sum of two DMP elements is DMP are inv…
Ergodic theory of amenable semigroup actions
Ali Ghaffari
In this paper, among other things, we state and prove the mean ergodic theorem for amenable semigroup algebras.
Topologically left invariant means on semigroup algebras
Ali Ghaffari
Let be the Banach algebra of all bounded regular Borel measures on a locally compact Hausdorff semitopological semigroup with variation norm and convolution as multiplic…
The Socle and finite dimensionality of some Banach algebras
Ali Ghaffari, Ali Reza Medghalchi
The purpose of this note is to describe some algebraic conditions on a Banach algebra which force it to be finite dimensional. One of the main results in Theorem~2 which states tha…
