| Research Abstract |
We study the geometry underlying a virtual turning point, which appears in exact WKB analysis. For this purpose, we have constructed a Riemann surface associated with a linear differential equation with a large parameter and a depth function which indicates dependency between new Stokes curves. As an application, we show that we can really obtain connection coefficients on all the new Stokes curves.
