I have tried to expand the Idea-section at orbit method a little.
also added further references to orbit method, including a pointer to Bruce Bartlett’s generalization to 2-group 2-representation.
I have added to the references at orbit method and Wilson loop a pointer to section 4 of
as a reference for details on how the Wilson loop observable is re-expressed as a path integral.
I have been adding some basic Definitions and constructions to orbit method, (but didn’t get to the main statement yet).
Then I started a section Formulation in higher geometry with some remarks on how these structures arise naturally from certain universal constructions on differential moduli stacks (with an eye towards applications in extended Chern-Simons theory with Wilson loop defects…)
This is still under construction. Don’t look at it yet if you don’t want to see imperfections.
Presumably you saw Chern-Simons Theory with Wilson Lines and Boundary in the BV-BFV Formalism. Lots of orbits going on there.
Oh yes, you did.
Hi David,
the formulation of Wilson loops by the orbit method is indicated already in Witten’s original article. The basic idea goes back to (at least) an article form 1978. The recent article that you point to discusses aspects of this in the context of BV-BRST formalism.
I have started to add some comments and some pointers to the literature at Chern-Simons theory – With Wilson line observables.
Have expanded further at orbit method. There is now a section reviewing traditional material:
and a section refining this to higher geometry:
I have spelled out more details at orbit method – Formulation in higher geometry.
Will now be porting this to geometry of physic – Prequantum gauge theory and gravity - Semantics layer.
