Abstract

The relation between the nn-recollements of stable categories of Gorenstein projective modules and the virtual Gorensteinness of algebras are investigated. Let A,BA,B, and CC be finite dimensional algebras. We prove that if the stable category of Gorenstein projective AA-modules admits a nn-recollement relative to that of BB and CC with n2n\geq 2, then AA is virtually Gorenstein if and only if so are BB and CC.
