Research
Yoshitsugu Takei is working on differential equations, particularly
on the exact WKB analysis of linear and nonlinear differential equations.
In collaboration with T. Aoki (Kinki Univ.) and T. Kawai (RIMS), he
has succeeded in describing the monodromic structure of solutions of
linear ordinary differential equations through the exact WKB analysis,
discovered the exact steepest descent method, and established the exact
WKB analysis of Painlevé equations. His current interest is to obtain
an explicit description for the resurgent-analytical structure of
WKB-type formal solutions of linear differential equations as well as
of Painlevé equations, and also to develop the exact WKB analysis for
various hierarchies of higher order Painlevé equations.
