设R是环,A=Mn(R),θ:A→ A是保零Jordan积的满可加映射,即如果x,y∈ A使得xy +yx= 0,则θ(x)θ(y)+ θ(y)θ(x)= 0.本文证明了:若R包含n ≥ 4,则θ = λ <$,其中λ = θ(1)是A的中心元,且<$:A→ A是Jordan同态.
LetRbe a ring,A=Mn(R) and θ:A→Aa surjective additive map preserving zero Jordan products, i.e. ifx,y∈Aare such thatxy+yx= 0, then θ(x)θ(y) + θ(y)θ(x) = 0. In this paper, we show that ifRcontainsandn≥ 4, then θ = λϕ, where λ = θ(1) is a central element ofAand ϕ:A→Ais a Jordan homomorphism.
