Stable Homotopy theory

This entry provides a hyperlinked index for

on stable homotopy theory in terms of stable ∞-categories.

Based on the theory of (∞,1)-categories as developed in his book Higher Topos Theory, the author studies here (,1)(\infty,1)-categories of “stable objects”, i.e. of objects that behave like spectra in that for each object XX there not only its loop space object ΩX\Omega X but also conversely, XX is the loop space object of another object ΣX\Sigma X.

The definition is very simple. The homotopy category of a stable (,1)(\infty,1)-category is shown to be a triangulated category: the comparatively complicated axioms of triangulated categories follow from the simple (,1)(\infty,1)-categorical axioms. Large chunks of homological algebra is then re-examined from the more natural point of view of stable (,1)(\infty,1)-categories.
