Virtual turning points and bifurcation of Stokes curves for higher order ordinary differential equations

Autor: Aoki, Takashi, Kawai, Takahiro, Sasaki, Shunsuke, Shudo, Akira, Takei, Yoshitsugu

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 turn
