  We review the theory of Co-Gorenstein algebras, which was introduced by
Beligiannis in the article "The Homological Theory of Contravariantly Finite
Subcategories: Gorenstein Categories, Auslander-Buchweitz Contexts and
(Co-)Stabilization". We show a connection between Co-Gorenstein algebras and
the Nakayama and Generalized Nakayama conjecture.
