A model category structure on the category of simplicial multicategories, preprint available at math.CT/0805.2611

Abstract. We establish a Quillen model structure on simplicial (symmetric) multicategories. It extends the model structure on sim-plicial categories due to J. Bergner [2]. We observe that our technique of proof enables us to prove a similar result for (symmetric) multicat-egories enriched over other monoidal model categories than simplicial sets. Examples include small categories, simplicial abelian groups and compactly generated Hausdorff spaces. 1
