    Does anyone agree that one should document the “Feynman Categories” in the sense of Kaufmann and Ward in the nLab?

    It puzzles me a little that despite extensive publications, extending back to 2013, and a talk, and despite the systematizing aspirations of Kaufmann–Ward’s work, the concept of Feynman category seems to yield zero search hits, both in the nLab, and in the nForum. Is this simply hazard?

    Just happened across this while I was searching for something else. In general, I don’t think there’s often any reason things AREN’T written up on the nlab, other than nobody has gotten around to it. As far as I can tell, people write things up on the nlab when they’re thinking about them, rather than in some systematic way meant to cover all the bases.

    However, Feynman categories do look interesting, so thanks for posting this!
