The hit problem of three variables for the cohomology of the classifying space BE_(s ) as a module over the mod 3 Steenrod Algebra at some low degrees

Abstract

The hit problem, set up by F. Peterson, finds a minimal set of generators for the polynomial algebra , as a module over the mod-2 Steenrod algebra. We study the extended hit problem for the cohomology of the classifying space over field , with at degrees d
