galois theory in homotopy theory
abstract:
we construct ramified families of curves to explicitly model the lubin-tate action, the action of a formal group law on its deformation space, for a maximal finite subgroup $g$. we will see that as a $g$-representation, this deformation space is a quotient of a regular representation of a finite cyclic group! this allows us to partially compute the $e_2$ page of the homotopy fixed point spectral sequence of the $k(h, p)$-local homotopy groups of spheres for height $h=p^{k-1}(p-1)$, for all such $h$ and $p$ simultaneously. thus, we resolve a 40 year old computational stalemate.
