Large-9 limit for winding Wilson loops on compact surfaces

About 9 years old · traced to

Let Σ\Sigma, UU, CC, aa, and c=area⁡(Σ)−ac=\operatorname{area}(\Sigma)-a be as in the preceding conjecture, with CC a simple closed curve in the topological disk UU. For n∈Zn\in\mathbb{Z}, let C(n)C^{(n)} be the loop obtained by traveling nn times around CC. The winding Wilson-loop conjecture. For every n∈Zn\in\mathbb{Z}, the limit

lim⁡N→∞E{tr⁡(hol⁡(C(n)))}\lim_{N\rightarrow\infty}\mathbb{E}\left\{\operatorname{tr}(\operatorname{hol}(C^{(n)}))\right\}

exists and depends continuously on aa and cc, and

lim⁡N→∞Var⁡{tr⁡(hol⁡(C(n)))}=0.\lim_{N\rightarrow\infty}\operatorname{Var}\left\{\operatorname{tr}(\operatorname{hol}(C^{(n)}))\right\}=0.

This strengthens the simple-closed-curve conjecture to loops with arbitrary integer winding and is intended to support the analysis of all topologically trivial loops with simple crossings. The supplied text does not state whether this extension has been resolved.
