“…So we have g 12 (Y Z) = Y h 22 (Z). Through a similar discussion as the proof of Claim 4, we obtain h 22 (Z) = Zh 22 (I 2 ) for all Z in B and g12 (Y ) = Y h 22 (I 2 ) for all Y in M.Thus we have thatφ X Y 0 Z = f 11 (I 1 )X f 11 (I 1 )Y 0 Zh 22 (I 2 ) = f 11 (I 1 )X Y h 22 (I 2 ) 0 Zh 22 (I 2 )for everyX Y 0 Z in J .So it is sufficient to show that f 11 (I 1 )X = Xf 11 (I 1 ) for all X in A, and h 22 (I 2 )Z = Zh 22 (I 2 ) for all Z in B. Since f 11 (I 1 )Y = Y h 22 (I 2 ) for all Y in M, we have f 11 (I 1 )XY = XY h 22 (I 2 ) = Xf 11 (I 1 )Y .…”

“…Thus, by Theorem 2.3 we have the following result which is a generalization of main result in [6]. Downloaded by [New York University] at 12:27 23 June 2015 Theorem 2.4 Let R be a prime ring with the unit 1 and a nontrivial idempotent p = 1 1 .…”

“…It is surprising that there do exist full-derivable points for some algebras. In [5,6], the authors shown that 'every nontrivial idempotent and left or right separating points are full-derivable points of a prime Banach algebra'. In [2], we proved that 'every nonzero operator is a full-derivable point of the Hilbert space nest algebra AlgN '.…”
