The Mahowald operator in the cohomology of the Steenrod algebra

D. C. Isaksen

We study the Mahowald operator M = ( g2, h03, - ) in the cohomology of the Steenrod algebra. We show that the operator interacts well with the cohomology of A(2), in both the classical and C-motivic contexts. This generalizes previous work of Margolis, Priddy, and Tangora.
