| Outline of Final Research Achievements |
In this project, we have studied the two topics: "Width of resonances for 2x2 Schrodinger operator with energy-level crossings" and "Transition probability for avoided crossings and Stokes geometry".
In the former project, we confirmed that energy-level crossing generates (complex-valued) resonances from (real-valued) embedded eigenvalues and moreover we obtained the precise semi-classical asymptotic expansion of the imaginary part of the resonances.
In the latter, we considered the confluence of turning points, which characterize Stokes geometries. We applied a semi-classical microlocal analysis to this problem, where a complex WKB analysis does not work well. We had spent much time to the control problem of two parameters (confluence and semi-classical), but we succeeded it in the final year.
