On the hit problem of rank five

Abstract

Let $P_q$ be the graded polynomial algebra ${\mathbb{F}}_2[x_1,x_2,\dots ,x_q]$ over the prime field of two elements, ${\mathbb{F}}_2$, with the degree of each $x_i$ being 1. We study the {\it hit Peterson problem} of finding a minimal set of generators for $P_q$ as a module over the mod-$2$ Steenrod algebra, $\mathcal{A}.$ In this note, we present the minimal sets of $\mathcal{A}$-generators for $P_5$ in the cases where the degree are sufficiently general.
