Abstract: | The notions of quasik-Gorenstein algebras and W t -approximation representations are introduced. The existence and uniqueness (up to projective equivalences) of W t -approximation representations over quasi k-Gorenstein algebras are established. Some applications of W t -approximation representations to homologically finite subcategories are given. |
