Stable graphs: Feynman diagrams and Deligne-Mumford space
I'm not sure exactly what the question is, but let me comment that lots of Feynman graphs with lots of different rules for labelling the vertices come up in QFT, as explained by Theo. From the QFT po …

What is the state in the WRT TQFT associated to a handlebody?
(Making this an answer, since it will be a little long, even though it doesn't actually answer the question.)
One thing to be aware of is that there are multiple ways to talk about this same TQFT. In …
