左模张量积的同态及其基础环的转移

Homomorphism of Tensor Product of Left Modules and Transfer of Its Basic Rings

本文在［１］的基础上，讨论了两个左模张量积的同态，左模和左模张量积的基础环的转移，逆转移。并给出了基础环逆转移的一个同构定理。

This paper discusses the homomorphism of tensor product of two left modules, the direct transfer and inverse transfer of left modules and tensor product of left modules, and offers an iso morphism theorem on inverse transfer of basic rings.
