摘要
Let R be a ring with a subset S. A mapping of R into itself is called strong commutativity-preserving (scp) on S, if [f(x), f(y)] = [x, y] for all x, y epsilon S. The main purpose of this paper is to describe the structure of the generalized derivations which are scp on some ideals and right ideals of a prime ring, respectively. The semiprime case is also considered.
