symmetric monoidal (∞,1)-category of spectra
monoid theory in algebra:
The concept of localization of a monoid, the localization of a category with a single object. Could be generalized to localization of monoid objects in a cartesian monoidal category . The localization of a ring is a localization of a monoid object in Ab.
Let be a commutative monoid object in and let be a commutative submonoid of . Then the localization of away from , , is the set of equivalences on , such that there is an element where .
Write for the equivalence class of . On this set, the product is defined by
Analogue of noncommutative localization for noncommutative monoid objects in instead of .
…
The group completion of a commutative monoid is the localization of away from .
