Higher derivations and jordan higher derivations of -rings
Abstract:
Let and be additive abelian groups. If there exists a map sending into , denote the image of by, simply, for all and , satisfying the following properties: for each and ,
(i) ; (ii) , and , then is called a -ring.
Let be a -ring and be an ideal of . We introduce the concept of higher derivations, Jordan higher derivations of , higher derivations, Jordan higher derivations of into and generalized higher derivations, Jordan generalized higher derivations of . Our main interests are finding appropriate conditions for a -ring in order to obtain that
(1) Jordan higher derivations and higher derivations of a -ring are the same,
(2) Jordan higher derivations and higher derivations of an ideal of a -ring, are identical, and
(3) Jordan generalized higher derivations and generalized higher derivations of a -ring are coincide.
