1.给定任何结合环A,人们可以从它的运算和元素构造一个新的环,即A的Jordan环,方法是将这个环中的乘积定义为对所有a,Bea都是a,b=ab+ba,其中乘积ab表示结合环A本身中a和b的乘积。如果R是任何环,无论是结合的还是非结合的,通过R的导数,我们指的是一个函数,‘,将R映射到自身,使得
1. Given any associative ring A one can construct from its operations and elements a new ring, the Jordan ring of A, by defining the product in this ring to be a o b=ab+ba for all a, bEA, where the product ab signifies the product of a and b in the associative ring A itself. If R is any ring, associative or otherwise, by a derivation of R we shall mean a function, ', mapping R into itself so that
