| Abstract: | The notion of I-sequences (introduced by Green) in the category of modules over finite-dimensional algebras is developed in this paper and particularly used to give an alternative proof for the results of Knörr concerning the existence and properties of relative projective covers in the category of modules over group algebras. |
