Elementary Abelian p-Groups”

ABSTRACT: For an odd prime p, the cohomology ring of an
elementary abelian p-group is polynomial tensor exterior. We show that the
ideal of essential classes is the Steenrod closure of the class generating the
top exterior power. As a module over the
polynomial algebra, the essential ideal is free on the set of M`ui invariants.
