Construction of Hypergeometric Solutions to the q-Painlevé Equations
Kenji Kajiwara, Tetsu Masuda, Masatoshi Noumi +2
Hypergeometric solutions to the q-Painlevé equations are constructed by direct linearization of disrcrete Riccati equations. The decoupling factors are explicitly determined so tha…
Hypergeometric solutions to the q-Painlevé equations
Kenji Kajiwara, Tetsu Masuda, Masatoshi Noumi +2
Hypergeometric solutions to seven q-Painlevé equations in Sakai's classification are constructed. Geometry of plane curves is used to reduce the q-Painlevé equations to the three-t…
Cubic Pencils and Painlevé Hamiltonians
Kenji Kajiwara, Tetsu Masuda, Masatoshi Noumi +2
We present a simple heuristic method to derive the Painlevé differential equations from the corresponding geometry of rational surafces. We also give a direct relationship between…
_10E_9 solution to the elliptic Painlev'e equation
Kenji Kajiwara, Masatoshi Noumi, Tetsu Masuda +2
A function formalism for Sakai's elliptic Painlev'e equation is presented. This establishes the equivalence between the two formulations by Sakai and by Ohta-Ramani-Grammaticos…
q-Painlevé systems arising from q-KP hierarchy
Kenji Kajiwara, Masatoshi Noumi, Yasuhiko Yamada
A system of q-Painlevé type equations with multi-time variables t_1,...,t_M is obtained as a similarity reduction of the N-reduced q-KP hierarchy. This system has affine Weyl group…
Discrete dynamical systems with symmetry
Kenji Kajiwara, Masatoshi Noumi, Yasuhiko Yamada
We give a birational realization of affine Weyl group of type . We apply this representation to construct some discrete integrable systems and d…
