Sahleh, Abbas; Zivari-Kazempour, Abbas Module actions on iterated duals of Banach algebras. (English) Zbl 1252.46039 ISRN Math. Anal. 2011, Article ID 439649, 6 p. (2011). Summary: Let \(\mathcal A\) be a Banach algebra and \(\mathcal A''\) its second dual equipped with the first Arens product. We consider three \(\mathcal A''\)-bimodule structures on the fourth dual of \(\mathcal A\). This paper discusses the situation that makes these structures coincide.
