The switch to Gmail has been an ongoing project for the past two years, Manager of IT Technical Communications Carlyn Chatfield said. "We monitor what our students are asking for, what other institutions are doing, and we watch what 's going on in the ...

The paper deals with the study of Z-symmetric manifolds (ZS)n admitting certain cases Schouten tensor (specifically: Ricci-recurrent, cyclic parallel, Codazzi type and covariantly constant), investigate some geometric physical properties manifold. Moreover, we also (ZS)4 spacetimes tensor. Finally, construct an example to verify our result.

Let R be an associative ring with center Z(R) , I a nonzero ideal of and  be automorphism  of . An 3-additive mapping M:RxRxR is called symmetric left -3-centralizer if M(u1y,u2 ,u3)=M(u1,u2,u3)(y) holds for all  y, u1, u2, u3 In this paper we shall investigate the  commutativity prime rings admitting satisfying any one following conditions : (i)M([u ,y], u3)  [(u), (y)...
