Abstract: We investigate the centralizers and Jordan derivations for com¬mutative subspace lattice algebras in von Neumann algebras. For any CSL subalgebra A of a von Neumann algebra, we prove that a (weak) Jordan centralizer Φ (i.e Φ : A → A is an additive mapping satisfying 2Φ (A2) = Φ(A) A + AΦ(A) for all A ∈ A) is automatically a centralizer. Similarly, we show that every Jordan derivation of A is a derivation. Additionally, we obtain concrete characterizations of centralizers for standard subalgebras of CSL algebras, and a stronger result is also obtained for standard subalgebras of nest algebras. © Theta, 2013.
