设是交换的诺特局部环。一个G生成的Gorenstein投射模称为IG-投射模,如果存在一个不可约满射或不可约单射。本文给出了Gorenstein投射猜想的一个注记:一个G-生成的IG-投射模是投射的当且仅当它是自正交的。
Letbe a commutative Noetherian local ring. A finitely generated Gorenstein projective-moduleis called IG-projective if there exists either an irreducible epimorphismor irreducible monomorphismwithbeing a projective-module. In this paper, we give a note on Gorenstein Projective Conjecture: a finitely generated IG-projective module is projective if and only if it is self-orthogonal.
