Abstract

We give a generalization of Quillen's S1SS^{-1}S construction for arbitrary EnE_n-monoids as an En1E_{n-1}-monoidal \infty-category and show that its realization models the group completion provided that n2n \geq 2. We will also show how this construction is related to a variety of other constructions of the group completion.
