摘要 设M是包含非平凡投影P的单位素*-环.证明了非线性双射ф:M→M,对所有A,B∈M,ф(AB+BA*)=ф(A)ф(B)+ф(B)ф(A)*当且仅当ф是*-环同构. Let M be a unital prime * - ring containing a nontrivial projection P. It is shown that a nonlinear bijeetive map Ф : M→M satisfies Ф ( AB + BA * ) = Ф ( A ) Ф (B) + Ф (B) Ф ( A ) * for all A, B ∈ M if and only if Ф is a * - ring isomorphism.
