Abstract:
For a Banach algebra A and a character on A, we have recently introduced and studied the notion of
-pseudo-amenability of A. Here, we give some characterizations of this notion in terms of derivations
from A into various Banach A-bimodules.
Keywords and phrases: Banach algebra, pseudo-amenable, approximate diagonal, -pseudo-amenable.
