Generalized derivations with power values on Lie ideals in rings and Banach algebras

, 2015
Let R be a 2-torsion free prime ring with center Z, right Utumi quotient ring U , generalized derivation F associated with a nonzero derivation d of R and L a Lie ideal of R. If F (uv)n = F (u)mF (v)l or F (uv)n = F (v)lF (u)m for all u, v ∈ L, where m,n,

A note on Jordan left *-centralizers in rings with involution

, 2015
Let R be a ring with involution. An additive mapping T : R → R is called a left ∗-centralizer (resp. Jordan left ∗-centralizer) if T (xy) = T (x)y∗ (resp.

On Gamma-derivations in the projective product of gamma rings

, 2015
This paper highlights many enlightening results on various Gamma-derivations in the projective product of Gamma-rings. If (X,  ) is the projective product of two Gamma-rings ( X1, 1  ) and ( X2 , 2  ), a pair of derivations D1 and D2 on ( X1, 1 ...
