In this paper some questions in the homotopy theory of model categories are answered. The important results of this paper are Theorems B, C and D which state that pushouts, sequential direct limits, and realizations of simplicial objects respect weak equivalences, provided sufficient cofibrancy is present. Section 1 presents a model category structure on the simplicial objects over a model category. This is done partly to provide a justification for the term cofibrant, as applied to certain… CONTINUE READING
