Feynman graphs, and nerve theorem for compact symmetric multicategories (extended abstract)
André Joyal, Joachim Kock
We describe a category of Feynman graphs and show how it relates to compact symmetric multicategories (coloured modular operads) just as linear orders relate to categories and root…

Coherence for weak units
André Joyal, Joachim Kock
We define weak units in a semi-monoidal 2-category $\CC$ as cancellable pseudo-idempotents: they are pairs where is an object such that tensoring with from either s…

Polynomial functors and polynomial monads
Nicola Gambino, Joachim Kock
We study polynomial functors over locally cartesian closed categories. After setting up the basic theory, we show how polynomial functors assemble into a double category, in fact a…
