Topic: Lawvere theories for operads


view this post on Zulip Rune Haugseng (Jun 21 2021 at 13:04):

Is there a characterization in the literature of the Lawvere theories that correspond to (algebras in Set for) operads (in Set)?

I presume you mean nonsymmetric operads rather than symmetric ones? Symmetric operads are treated in Szawiel–Zawadowski's Theories of analytic monads, but I haven't come across a similar result for nonsymmetric operads.

I am mainly interested in symmetric operads, so this looks like exactly what I wanted (at least in the 1-sorted case), thanks!
