چکیده

1.1. The simplicial localization. The localization of a category C with respect to a subcategory W is the category C[W-‘1 which has the same objects as C and is obtained from C by formally inverting the maps of W. Our purpose here is to show that C[W-‘1 reflects just one aspect of a much richer object, the simplicial localization LC. This simplicial localization LC is a simplicial category with in each dimension the same objects as C (i.e. for every two objects X, YE C, the maps X + YE LC form a simplicial set LC(X, Y)), which has the localization C[W-‘1 as its “category of components”. By this we mean that, for every two objects X, YE C,

A Characterization of Simplicial Localization Functors and a Discussion of Dk Equivalences

In a previous paper we lifted Charles Rezk’s complete Segal model structure on the category of simplicial spaces to a Quillen equivalent one on the category of “relative categories.” Here, we characterize simplicial localization functors among relative functors from relative categories to simplicial categories as any choice of homotopy inverse to the delocalization functor of Dwyer and the seco...

On the structure of simplicial categories associated to quasi - categories

The homotopy coherent nerve from simplicial categories to simplicial sets and its left adjoint C are important to the study of (∞, 1)-categories because they provide a means for comparing two models of their respective homotopy theories, giving a Quillen equivalence between the model structures for quasi-categories and simplicial categories. The functor C also gives a cofibrant replacement for ...

A Galois Theory with Stable Units for Simplicial Sets

We recall and reformulate certain known constructions, in order to make a convenient setting for obtaining generalized monotone-light factorizations in the sense of A. Carboni, G. Janelidze, G. M. Kelly and R. Paré. This setting is used to study the existence of monotone-light factorizations both in categories of simplicial objects and in categories of internal categories. It is shown that ther...

n-RELATIVE CATEGORIES: A MODEL FOR THE HOMOTOPY THEORY OF n-FOLD HOMOTOPY THEORIES

We introduce, for every integer n ≥ 1, the notion of an n-relative category and show that the category of the small n-relative categories is a model for the homotopy theory of n-fold homotopy theories, i.e. homotopy theories of . . . of homotopy theories. 1. Background and motivation In this introduction we • recall some results of (higher) homotopy theory, and • explain how they led to the cur...
