A graduate-level introduction to the homotopical technology in use at the forefront of modern algebraic topology.

This book contains some important new contributions to the theory of structured ring spectra.

This book introduces a new point-set level approach to stable homotopy theory that has already had many applications and promises to have a lasting impact on th

A comprehensive, self-contained approach to global equivariant homotopy theory, with many detailed examples and sample calculations.

The author introduces the notion of a Galois extension of commutative $S$-algebras ($E_\infty$ ring spectra), often localized with respect to a fixed homology t
