On the unit of a monoidal model category
arXiv:1411.1349 · doi:10.1016/j.topol.2015.05.006
Abstract
In this paper we show how to modify cofibrations in a monoidal model category so that the tensor unit becomes cofibrant while keeping the same weak equivalences. We obtain aplications to enriched categories and coloured operads in stable homotopy theory.
