Homotopy theory of non-symmetric operads
arXiv:1101.1634 · doi:10.2140/agt.2011.11.1541
Abstract
We endow categories of non-symmetric operads with natural model structures. We work with no restriction on our operads and only assume the usual hypotheses for model categories with a symmetric monoidal structure. We also study categories of algebras over these operads in enriched non-symmetric monoidal model categories.
