Let R be a commutative (possibly non-Noetherian) ring (in order to make things less
technical) and C a semidualizing R-module. In this article, we introduce and investigate the
notion of GC-injective (GC-projective) complexes. This extends Enochs and García Rozas's
notion of Gorenstein injective (Gorenstein projective) complexes. We then show that a
complex X is GC-injective (GC-projective) if and only if X m is a GC-injective (GC-projective)
module for each m∈ ℤ.
