摘要
由可知,从已知代数模的扩张U出发,便可得一广义导子f。反之,利用这个广义导子f,我们也可构造出一个代数模的扩张U＇。本文证明了这两个代数模U与U＇是同构的。并给出了由因子系构造代数的扩张的一个方法。
By[1],from an extension U of algebra-module,We may get a generalized derivation f. conversely,we use this generalized derivation f,to may construct a extension U' of algebra-module. In this present paper,the author proves that U and U' are isomorphic;Finally the author gives a methed by factor system construction the extension of algebras.
