摘要：

We characterize surjective maps on , the space of all bounded operators on an infinite-dimensional complex Banach space X, which satisfy "r (T-S) (x) = 0 if and only if for every and ". We do not assume to be linear, or even additive, and thus this characterization is a step forward in generalizing some preceding results.
