Abstract
If is a nonzero finitely generated module over a commutative Noetherian local ring such that has finite injective dimension and finite Gorenstein dimension, then it follows from a result of Holm that has finite projective dimension, and hence a result of Foxby implies that is Gorenstein. We investigate whether the same conclusion holds for nonzero finitely generated modules that have finite injective dimension and finite reducing Gorenstein dimension, where the reducing Gorenstein dimension is a finer invariant than the classical Gorenstein dimension, in general.
