Se p 20 06 Cofibrations in Homotopy Theory
نویسنده
چکیده
We define Anderson-Brown-Cisinski (ABC) cofibration categories, and construct homotopy colimits of diagrams of objects in ABC cofibraction categories. Homotopy colimits for Quillen model categories are obtained as a particular case. We attach to each ABC cofibration category a right derivator. A dual theory is developed for homotopy limits in ABC fibration categories and for left derivators. These constructions provide a natural framework for 'doing homotopy theory' in ABC (co)fibration categories.

Working in an arbitrary pointed proper model category, we describe the cofibrations that have an obstruction theory with respect to all fibrations. Up to weak equivalence, retract, and cobase change, they are the cofibrations with weakly contractible target. Equivalently, they are the retracts of principal cofibrations. Without properness, the same classification holds for cofibrations with cof...

متن کاملCofibrations and Bicofibrations
The paper deals with the correlated concepts of cofibration and bicofibration in C∗-algebra theory. We study cofibrations of C∗-algebras introduced by Claude Schochet in [9] (see also [7]). Cofibrations are characterized by means of the mapping cylinder C∗-algebras. We also define and analyse the notion of bicofibration for C∗-algebras based on the topological model from [8] (see also [5]). As ...
متن کاملSimplicial approximation
The purpose of this paper is to display a different approach to the construction of the homotopy theory of simplicial sets and the corresponding equivalence with the homotopy theory of topological spaces. This approach is an alternative to existing published proofs [4],[11], but is of a more classical flavour in that it depends heavily on simplicial approximation techniques. The verification of...
متن کاملHow (non-)unique Is the Choice of Cofibrations?
The question that serves as the title is to be understood in the context of Quillen model categories: having fixed the category of models and the subcategory of weak equivalences, how much ambiguity is there in finding suitable fibration and cofibration classes? Already for simplicial sets, infinitely many different subclasses of the monomorphisms can serve as cofibrations (with the usual weak ...
