摘要
Let A and B be two factor von Neumann algebras. In this paper, we proved that a bijective mapping phi: A -> B satisfies phi(a circle b - ba*) = phi(a) circle phi(b) - phi(b)phi(a)* (where circle is the special Jordan product on A and B, respectively), for all elementsa,b is an element of A, if and only if phi is a*-ring isomorphism. In particular, if the von Neumann algebras A and B are type I factors, then phi is a unitary isomorphism or a conjugate unitary isomorphism.
