∞-Operads as Analytic Monads
David Gepner, Rune Haugseng, Joachim Kock
We develop an ∞-categorical version of the classical theory of polynomial and analytic functors, initial algebras, and free monads.
Using this machinery, we provide a new model for ∞-operads, namely ∞-operads as analytic monads.
We justify this definition by proving that the ∞-category of analytic monads is equivalent to that of dendroidal Segal spaces, which are known to be equivalent to the other existing models for ∞-operads.
