摘要：
Delta-finitistic dimensions of standardly stratified algebras are defined similarly to properly stratified algebras. It is proved that the finitistic dimension for any standardly stratified algebra is bounded by the sum of the Delta-finitistic dimension and the del-good filtration dimension. Finally, the del-good filtration dimension of standardly stratified algebras is equal to the del-good filtration dimension of their Ringel duals.
