Virtual turning points and bifurcation of Stokes curves for higher order ordinary differential equations
For a higher order linear ordinary differential operator P , its Stokes curve bifurcates in general when it hits another turning point of P . This phenomenon is most neatly understandable by taking into account Stokes curves emanating from virtual turning points, together with those from ordinary turning points. This understanding of the bifurcation of a Stokes curve plays an important role in ...
متن کاملOn the complete description of the Stokes geometry for the first Painlevé hierarchy
with our sincerest congratulations on his being awarded Prix de l’Etat (Academie des Science). One of the central issues of this article is the introduction of the notion of virtual turning points for higher order Painlevé equations, and two of the authors (Kawai and Takei), together with T. Aoki, fondly remember the stimulating and comfortable conference (Algebraic analysis of singular perturb...
متن کاملOn global aspects of exact WKB analysis of operators admitting infinitely many phases
A case-study of the Stokes geometry in the large is given for some concrete examples of WKB type operators that admit infinitely many phases. In all the examples discussed in this article virtual turning points and new Stokes curves emanating from them neatly resolve the trouble we encounter. Some computerassisted study of the configuration of the steepest descent paths is employed to show that...
متن کاملOn the fourth order PI equation and coalescing phenomena of nonlinear turning points
In this report we present a conjecture for the fourth order PI equation with a large parameter to show its importance in the exact WKB analysis. The conjecture is related to coalescing phenomena of turning points and can be regarded as a nonlinear analogue of Hirose’s result ([9]) for the Pearcey system. We also discuss some relations between the conjecture and Dubrovin’s result ([7]) for the K...
متن کاملEnergy splitting in symmetric double-well potentials
The quantum mechanical tunnelling in a smooth symmetric double-well potential is a long-standing and well-known problem. Three methods have been proposed to calculate the energy splitting: the instanton method @1,2#, the WKB approximation @3,4# and numerical calculation @4–6#. The instanton method is helpful to understand the physical insight of quantum tunnelling, but the validity is restricte...
