Tensor Product 에 있어서의 semi-exact
이인석,배철곤,민강주 한국수학교육학회 1973 수학교육 Vol.12 No.1
In this paper, we want to verify some properties in tensor product. It is interesting to think semi-exact sequence in tensor product by [3]. Moreover no hardness is there in process and we want to discuss the commutativity in tensor product. For a certain semi-exact sequence, if we product arbitrary Abelian group for each group then the tensor product will do or not. Here, we have positive answer. At first we define the semi-exact sequence as following.
