交错环和交错代数1 aitettla幼犯d雌s叨d川邵b”.;助‘T印.叮娜助砚”山田叨皿叨，曦讨J 孪拳所(al temative ring)是指每两个元素都生成一个结合子环的环;孪考华熬(al ter”ativeai二玩a)是(线性)代数并且是交错环.根据E.Artin的一个定理，所有交错环的类由如下一组等式定义: (习)y”x切)(右交错性); (xx)y二x(却)(左交错性).于是，交错环形成一个簇.在这种环里，结合子(ass呱ator)(结合性的亏量) (x，少，:)=(xy卜一x恤)是其自变元的一个斜对称〔交错)函数，这个事实表明使用术语“交错环”是合理的. 交错环的第一个例子是Ca尹ey数(Caylcy num-悦巧)，它作成一个交错除环(幻忱n犯ti说s处阴一几城)或交错体，即有单位元的交错环且对于任意b和a笋0，方程ax=b和ya=b有唯一的解.交错除环在射影平面的理论中起着实质性的作用，这是因为一个射影平面是一个Motlfa飞平面(Mdufangp场能)(即关于某一直线的平移平面)，当且仅当其三元环的任何坐标化是交错除环.在一个有单位元的环R中，如果每个非零元素均可逆且对任意a，b〔R均有等式a一’(ab)二乙(或者，(b a)a一’=b)，则R是交错除环.任何交错除环或者是结合的，或者是其中心上的Ca洲ey一Di改50.代数(Qyley-众汰阳n爽灼ra). 每个单交错环也或者是结合环，或者是其中心上的Cayley一Di由on代数(在这种情形下，此代数未必是体).结合环和本原交错环都被Cayley·Di山on代数所穷尽.所有素交错环R(如果3R护0)或是结合环，或是Cayley一Dickson环. 在相似的条件下，交错环的许多性质本质上不同于结合环.例如，如果R是交错环，A和B是其右理想，则其积月丑未必是右理想，即使A是双边理想也如此.但是，两个双边理想的积仍是双边理想.交错环与结合环的差异也强烈地体现在这样的事实之中:由于括号放的位置不同，元素的积或是零或非零，从而交错环有各种幂零性.通常在交错环中使用如下几种幕零性:可解性(s olvabilit刃(环R称为具有指数m的可解子(s ulvable ringl如果存在自然数。
