Abstract

We investigate the centralizers and Jordan derivations for commutative subspace lattice algebras in von Neumann algebras. For any CSL subalgebra A of a von Neumann algebra, we prove that a (weak) Jordan centralizer Phi (i.e Phi : A - > A is an additive mapping satisfying 2 Phi(A(2)) Phi(A)A + A Phi(A) for all A is an element of 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.
