My mathematically-oriented work generally explores discrete geometric and probabilistic themes in physics, computation, and communication. Jack of most trades, master of none.

I can be reached at sh#eqnets#com (make the obvious substitutions for #).

Such integrals crop up in lattice gauge theory, for which see, e.g. Creutz's book.

comment Synthetic vs. classical differential geometry
As someone who doesn't actually know any SDG, it seems like one of SDG's most attractive practical aspects could/would be for proving theorems in an interactive proof assistant (at least this notion was why I bought an as-yet unread book on the topic).
