Abstract

The purpose of this paper is to establish an embedding of QM (A), the Banach space of all quasi-multipliers on A, in the second conjugate space A** of a Banach algebra A, which extends the well-known embedding of the left multipliers (right multipliers) of A in A**. We also prove that, for a dual B*-algebra, QM(A) is isometrically isomorphic to A**.
