WKB periods for higher order ODE and TBA equations
Katsushi Ito, Takayasu Kondo, Kohei Kuroda +1
We study the WKB periods for the -th order ordinary differential equation (ODE) which is obtained by the conformal limit of the linear problem associated with the $A_r^{(1)}…

ODE/IM correspondence for affine Lie algebras: A numerical approach
Katsushi Ito, Takayasu Kondo, Kohei Kuroda +1
We study numerically the ODE/IM correspondence for untwisted affine Lie algebras associated with simple Lie algebras including exceptional type. We consider the linear problem obta…
