Speaker: Joachim Kock (UAB) Title: Infinityoperads as polynomial monads Place: Seminari C3b/158 Date: 22th September at 12:00 Abstract: Lurie's infinityoperads are defined as certain Gammaspaces, in the spirit of MayThomason. A different approach to infinity operads is due to Cisinski and Moerdijk in terms of dendroidal Segal spaces. After outlining these approaches, I will explain a new model for infinityoperads, given in terms of polynomial monads. This provides an infinity version of the classical viewpoint that operads are monoids in the monoidal category of species/analytic functors under the substitution product. Leaving out the technical details, I will explain the ideas behind the proof that the infinitycategory of analytic monads is equivalent to the infinitycategory of dendroidal Segal spaces. This is joint work with David Gepner and Rune Haugseng.
