Nilpotence for modules over the mod 2 Steenrod algebra. I
Let \(A\) be the mod 2 Steenrod algebra and let \(M\) be a finite \(A\)-module. This paper characterizes the nilpotent elements of \(\text{Ext}^{**}_{A}(M,M)\) as those elements \(z\) such that for all elementary sub-Hopf algebras \(E\) of \(A\) the images \(i_{E}(z)\) are nilpotent.
