چکیده

The list of q-Painlevé equations we are going to investigate is given in section 3 below. We remark that these q-Painlevé equations were discovered through various approaches to discrete Painlevé equations, including singularity confinement analysis, compatibility conditions of linear difference equations, affine Weyl group symmetries and τ-functions on the lattices. Also, in Sakai’s framework [2], each of these q-Painlevé equations is constructed in a unified manner as the birational action of a translation of the corresponding affine Weyl group on a certain family of rational surfaces. In [4] we have introduced the formulation of discrete Painlevé equations based on the geometry of plane curves on P2. On that basis we were able in the first part of [1] to find suitable coordinates for linearization of the q-Painlevé equations into three-term relations of hypergeometric functions. As a result we obtained the following degeneration diagram of basic hypergeometric functions corresponding to (1):

Hypergeometric solutions to the q-Painlevé equations

It is well-known that the continuous Painlevé equations PJ (J=II,. . .,VI) admit particular solutions expressible in terms of various hypergeometric functions. The coalescence cascade of hypergeometric functions, from the Gauss hypergeometric function to the Airy function, corresponds to that of Painlevé equations, from PVI to PII [1]. The similar situation is expected for the discrete Painlevé...

A q-anaolg of the sixth Painlevé equation

A q-difference analog of the sixth Painlevé equation is presented. It arises as the condition for preserving the connection matrix of linear q-difference equations, in close analogy with the monodromy preserving deformation of linear differential equations. The continuous limit and special solutions in terms of q-hypergeometric functions are also discussed.

Grothendieck’s Dessins D’enfants, Their Deformations, and Algebraic Solutions of the Sixth Painlevé and Gauss Hypergeometric Equations

Grothendieck’s dessins d’enfants are applied to the theory of the sixth Painlevé and Gauss hypergeometric functions, two classical special functions of isomonodromy type. It is shown that higher-order transformations and the Schwarz table for the Gauss hypergeometric function are closely related to some particular Bely̆ı functions. Moreover, deformations of the dessins d’enfants are introduced, ...

-Surface q-Painlevé IV Equation

We consider a q-Painlevé IV equation which is the A (1) 4 -surface type in the Sakai’s classification. We find three distinct types of classical solutions with determinantal structures whose elements are basic hypergeometric functions. Two of them are expressed by 2φ1 basic hypergeometric series and the other is given by 2ψ2 bilateral basic hypergeometric series.
