Some identities involving multiplicative semiderivations on ideals
(Hacettepe Journal of Mathematics & Statistics, 2021)
Let R be a prime ring and I be a nonzero ideal of R. A mapping d : R → R is called a
multiplicative semiderivation if there exists a function g : R → R such that (i) d(xy) =
d(x)g(y)+xd(y) = d(x)y +g(x)d(y) and (ii) ...
