Title: Infinity-operads as polynomial monads
Place: Seminari C3b/158
Date:
22th September at 12:00
Abstract:
Lurie's infinity-operads are defined as certain Gamma-spaces, in the spirit of May-Thomason.  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 infinity-operads, 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 infinity-category of analytic monads is equivalent to the infinity-category of dendroidal Segal spaces.  This is joint work with David Gepner and Rune Haugseng.
