摘要：

Let theta : A(sa) -> B-sa be a bijective real linear zero product preserver between the self-adjoint parts of two (complex) C*-algebras. Suppose. preserves commutativity in two directions (i.e., ab = ba if and only if theta(a)theta(b) = theta(b)theta(a)). We show that theta is automatically continuous. More precisely, there is an invertible central self-adjoint multiplier h of B, and a real linear Jordan isomorphism J : A(sa) -> B-sa such that theta = hJ.
