The localization of orthogonal calculus with respect to homology
arXiv:2109.13806 · doi:10.2140/agt.2024.24.1505
Abstract
For a set of maps of based spaces we construct a version of Weiss' orthogonal calculus which depends only on the -local homotopy type of the functor involved. We show that -local homogeneous functors of degree are equivalent to levelwise -local spectra with an action of the orthogonal group via a zigzag of Quillen equivalences between appropriate model categories. Our theory specialises to homological localizations and nullifications at a based space. We give a variety of applications including a reformulation of the Telescope Conjecture in terms of our local orthogonal calculus and a calculus version of Postnikov sections. Our results also apply when considering the orthogonal calculus for functors which take values in spectra.
