Abstract
Koszul modules over Noetherian local rings were introduced by Herzog and Iyengar and they possess good homological properties, for instance their Poincare' series is rational. It is an interesting problem to characterize classes of Koszul modules. Following the idea traced by Avramov, Iyengar and Sega, we take advantage of the existence of special filtration on for proving that large classes of -modules over Koszul rings are Koszul modules. By using this tool we reprove and extend some results obtained by Fitzgerald.
