论文摘要
让$ a $为{\ rm char} $(f)\ ne 2 $的字段$ f $上的代数。如果$ a $是由$ [[a,a],[a,a]] $生成的代数 skew-symmetric bilinear map $Φ:A\times A\to X$, where $X$ is an arbitrary vector space over $F$, the condition that $Φ(x^2,x)=0 $ for all $x\in A$ implies that $Φ(xy,z) +Φ(zx,y) + Φ(yz,x)=0$ for all $x,y,z\in A$. This is applicable to the question of whether $A$ is zero Lie product determined, and is also used in proving that a Jordan homomorphism from $A$ onto a semiprime algebra $B$ is the sum of a homomorphism and an antihomomorphism.
Let $A$ be an algebra over a field $F$ with {\rm char}$(F)\ne 2$. If $A$ is generated as an algebra by $[[A,A],[A,A]]$, then for every skew-symmetric bilinear map $Φ:A\times A\to X$, where $X$ is an arbitrary vector space over $F$, the condition that $Φ(x^2,x)=0 $ for all $x\in A$ implies that $Φ(xy,z) +Φ(zx,y) + Φ(yz,x)=0$ for all $x,y,z\in A$. This is applicable to the question of whether $A$ is zero Lie product determined, and is also used in proving that a Jordan homomorphism from $A$ onto a semiprime algebra $B$ is the sum of a homomorphism and an antihomomorphism.
