Title: On a category of extensions whose endomorphism rings have at most four maximal ideals
Title: 关于其自同构环最多只有四个极大理想的扩张范畴
Abstract: We describe the endomorphism ring of a short exact sequences $0 \to A_R \to B_R \to C_R \to 0$ with $A_R$ and $C_R$ uniserial modules and the behavior of these short exact sequences as far as their direct sums are concerned.
