The exact WKB analytic continuation conjecture for strongly GMN spectral curves
The exact WKB analytic continuation conjecture for strongly GMN spectral curves
Let be a WKB-regular -flat connection with strongly GMN spectral curve, let be a WKB formal solution, and let be its Borel–Laplace dual. Let be an unobstructed angle whose existence is assured by the paper's main theorem. Exact WKB analytic continuation conjecture. If is not on the Stokes graph at , then is analytically continuable on and is Laplace transformable in direction . If are the Stokes trees at passing through , then the first sheet of the analytic continuation of is smooth on
This is proposed as a higher-order exact WKB statement: away from the Stokes graph one expects Borel summability, while Stokes trees describe the singularities excluded from the first-sheet continuation. The source supplies no proof or resolution, so the conjecture remains open.
