%X 设 Q 是一个有限无圈箭图,R是一个环,Rep(Q,R)是 Q 的左 R- 模表示范畴。本文描述了 Rep(Q,R) 中相对于余挠对的 Gorenstein 投射表示。具体地,我们证明了X∈Rep(Q,R) 是相对于(A,B)的 Gorenstein 投射表示当且仅当对任意的i∈??0,是单同态,并且X(i),CokerφiX是相对于 (A,B)的Gorenstein投射模.
Let Q be a finite acyclic quiver, R a ring, and Rep(Q,R) the category of left R-module representations of Q. This paper characterizes Gorenstein projective representations in Rep(Q, R) relative to cotorsion pairs. Specifically, we prove that a representation X∈Rep(Q, R) is Gorenstein projective relative to (A, B) if and only if} for every vertex i∈Q0, the canonical morphism
