$\mathrm{U}(1{)}^n$ Chern-Simons theory: partition function, reciprocity formula and Chern-Simons duality

Han-Miru Kim, Philippe Mathieu, Michail Tagaris +1

The $\mathrm{U}(1)$ Chern-Simons theory can be extended to a topological $\mathrm{U}(1{)}^n$ theory by taking a combination of Chern-Simons and BF actions, the mixing being achieved…
