Abstract

In this article, we introduce the notion of Lie triple centralizer as follows. Let (Figure presented.) be an algebra, and (Figure presented.) be a linear mapping. We say that ϕ is a Lie triple centralizer whenever (Figure presented.) for all (Figure presented.). Then we characterize the general form of Lie triple centralizers on a generalized matrix algebra (Figure presented.) and under some mild conditions on (Figure presented.) we present the necessary and sufficient conditions for a Lie triple centralizer to be proper. As an application of our results, we characterize generalized Lie triple derivations on generalized matrix algebras.
