Let $A$ be the mod $p$ Steenrod algebra, let $M$ be an unstable $A$-module, and let $P_s=H^*(B(\mathbb Z/p)^s)$. Let $\mathscr{R}_sM$ be the $s$-th Singer construction and let…

Let $M$ be an unstable module over the Steenrod algebra $\mathscr{A}$ at the prime two, let $s>2$ be an integer, and let $R_sM$ denote the Singer construction, viewed as a submodul…
