Abstract
Given a ring , we have a classical result stating that the ordinary category of modules is the abelianization of the category of augmented -algebras. Analogously, using the framework of infinity categories and higher algebra, Francis showed that the infinity category of -modules is the stabilization of the infinity category of augmented -algebras. In this work we show a dual result for coalgebras over a cooperad : namely that given a coalgebra , comodules over are the costabilization of coalgebras over , which is the universal stable category with a finite colimit preserving functor to coalgebras over .
