Let D be a strongly double triangle subspace lattice on a nonzero complex reflexive Banach space. In this paper, we characterize the linear maps (5, T: AlgD -AlgD satisfying (5(A)B + AT(B) = 0 for any A, B E AlgD with AB = 0. This result can be used to characterize linear maps derivable (centralized) at zero point and local centralizers on AlgD, respectively.
