Infinite families of higher torsion in the homotopy groups of Moore spaces

Steven Amelotte, Frederick R Cohen and Yuxin Luo

Algebraic & Geometric Topology 23 (2023) 2389–2414

We give a refinement of the stable Snaith splitting of the double loop space of a Moore space and use it to construct infinite periodic families of elements of order pr+1 in the homotopy groups of mod pr Moore spaces. For odd primes p, our splitting implies that the homotopy groups of the mod pr+1 Moore spectrum are summands of the unstable homotopy groups of each mod pr Moore space.
