Abstract

In this note, we study some properties of the filtration of the Steenrod algebra defined from the excess of admissible monomials. We give several conditions on a cocommutative graded Hopf algebra A which enable us to develop the theory of unstable A–modules.

Keywords

Steenrod algebra, unstable module
