Idea

Spectral algebraic geometry (or maybe E-∞ geometry) is the theory of homotopical algebraic geometry specialized to the (infinity,1)-category of spectra. Hence it is a generalization of ordinary algebraic geometry where instead of commutative rings, spectral schemes are locally modelled on commutative ring spectra.

Applications

Elliptic cohomology

Historically, the first application of spectral algebraic geometry was in the study of elliptic cohomology and topological modular forms. In particular it allowed the construction and study of the tmf spectrum as a certain derived moduli stack of derived elliptic curves. This construction is based on the Artin-Lurie representability theorem. See
