Research
Yoshitsugu Takei is working on differential equations, particularly
on the exact WKB analysis of linear differential equations and nonlinear
differential equations. In collaboration with T. Aoki (Kinki Univ.) and
T. Kawai (RIMS), he has discussed the monodromic structure of solutions
of linear ordinary differential equations through the exact WKB analysis
and the exact steepest descent method, and also developed the exact WKB
analysis for traditional 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 extend the exact WKB analysis to
various hierarchies of higher order Painlevé equations.
