英文摘要	Let be a local homomorphism and X a homologically finite S-complex. Iyengar and Sather-Wagstaff defined the G-dimension and projective dimension of X over by Cohen factorizations and Avramov, Iyengar, and Miller introduced the injective dimension of X over In this article, we define the Gorenstein injective dimension of X over The Bass equality for the Gorenstein injective dimension over local homomorphism is obtained, which generalizes a result of Christensen and Sather-Wagstaff. Some other known results are generalized. For instance, if is finite, then it is shown that This is analogous to a theorem of Holm.
