New paper πŸŽ‰πŸŽ‰
About coherence πŸ₯±πŸ’€β‰οΈ

joint work with Nick Gurski
https://arxiv.org/abs/2312.11261

The title is:
Universal pseudomorphisms, [*deep breath*]
with applications to diagrammatic coherence for braided and symmetric monoidal functors πŸ™ƒπŸ˜Έ

I've always thought coherence theorems sound boring, but actually they're good! In this paper we take a problem that is hard (coherence for structured functors), do a *bunch* of really abstract stuff (2-monad theory), and come out with a solution that makes your life* significantly better.

[*Here, "your life" means the part of your life you spend checking diagrams of braided monoidal functors. Or, more generally, pseudomorphisms for algebras over a 2-monad.]

Almost 1/5 of this paper is dedicated to real, genuine examples, and that's what I want to focus on below. I'll say just a bit about the more abstract machinery on which the examples are based. If you've been following along, this is the culmination of my series "weird facts about monoidal functors and coherence" [1,2,3,4].

Universal pseudomorphisms, with applications to diagrammatic coherence for braided and symmetric monoidal functors

This work introduces a general theory of universal pseudomorphisms and develops their connection to diagrammatic coherence. The main results give hypotheses under which pseudomorphism coherence is equivalent to the coherence theory of strict algebras. Applications include diagrammatic coherence for plain, symmetric, and braided monoidal functors. The final sections include a variety of examples.

- A #braided #monoidal category is called symmetric if { \gamma } also satisfies {gamms _{B,A}\circ \gamma _{A,B}=Id} for all pairs of objects { A, B}. In this case action of { \gamma } on an { N}-fold tensor product factors through the symmetric group
