$\mathrm{tmf}$–based Mahowald invariants

Abstract

The $2$ –primary homotopy $β$ –family, defined as the collection of Mahowald invariants of Mahowald invariants of $2^{i}$ for $i \geq 1$ , is an infinite collection of periodic elements in the stable homotopy groups of spheres. We calculate $tmf$ –based approximations to this family. Our calculations combine an analysis of the Atiyah–Hirzebruch spectral sequence for the Tate construction of $tmf$ with trivial $C_{2}$ –action and Behrens’ filtered Mahowald invariant machinery.
