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 φ i X : a Q 1 i %K 箭图,余挠对,相对于余挠对的Gorenstein投射表示
