摘要

Let \({\mathcal {S}}\) S and \({\mathfrak {B}}\) B be two unital \(*\) -algebras such that \({\mathcal {S}}\) S has a nontrivial projection. In the present article, we demonstrate, under certain restrictions that if a bijective map \(\Delta :{\mathcal {S}}\rightarrow {\mathfrak {B}}\) Δ : S B satisfies \(\Delta (M\diamond N \circ W) = \Delta (M)\diamond \Delta (N)\circ \Delta (W)\) Δ ( M N W ) = Δ ( M ) Δ ( N ) Δ ( W ) for all \(M, N, W \in {\mathcal {S}}\) M , N , W S , then \(\Delta\) Δ is a \(*\) -preserving ring isomorphism. As an application, we will describe these mappings on factor von Neumann algebras.
