... The extension of m on normed spaces and the concept of regularity of m were introduced by Richard Arens in [1] and [2]. Some characterizations for the Arens regularity of bounded bilinear map m and Banach algebra A are proved in [3], [4], [5], [9], [11], [12] and [13]. Theorem 5 Let f : X × Y × Z −→ W be a bounded tri-linear mapping and let m : Y ×Z −→ X * be a bounded bilinear mapping such that m(y, z) = f s * (w * , y, z), for every y ∈ Y, z ∈ Z and w * ∈ W * . ...
