چکیده
|
We introduce some new concepts as left-weak*-weak convergence property [lw*wc-property] and right-weak*-weak convergence property [rw*wc-property] for banach algebra a. suppose that a and a**, respectively, have rw*wc-property and lw*wc-property, then if a** is weakly amenable, it follows that a is weakly amenable. let d : ato a** be a surjective derivation. if d'' is a derivation, then a is arens regular.
