nLab globally equivariant spectrum

Idea

An object in the global equivariant stable homotopy theory.

Hence a spectrum compatibly equipped with the structure of a $G$-equivariant spectrum as $G$ ranges over a suitable given class of groups.

Examples

• The global equivariant sphere spectrum for all the cyclic groups over the circle group is canonically a cyclotomic spectrum and as such is the tensor unit in the monoidal (infinity,1)-category of cyclotomic spectra (see there).
