We identify the Goodwillie approximations of the circle as infinite loop spaces, using work of Behrens and Kuhn on the Whitehead conjecture. This reduces the computation of their homotopy groups to a stable problem, accessible through the Adams spectral sequence and computer calculations. We also develop a Goodwillie-calculus analogue of the Gray sequence relating successive stages of the tower.

We develop foundations for metastable homotopy theory using Heuts' 2-truncated Tate coalgebras.

We study natural transformations between functors built from reduced symmetric powers of pointed spaces. Using Goodwillie calculus, we develop a framework for computing their homotopy groups and carry out explicit rational and integral calculations, motivated by a connection with Ext groups between functors from free groups to abelian groups.
Some of these calculations subsequently appeared in Gregory Arone’s paper Polynomial functors from free groups to a stable infinity-category (see examples 12.11).
