The Lattice Structure of Connection Preserving Deformations for q-Painlev\'e Equations I
Abstract
We wish to explore a link between the Lax integrability of the -Painlev\'e equations and the symmetries of the -Painlev\'e equations. We shall demonstrate that the connection preserving deformations that give rise to the -Painlev\'e equations may be thought of as elements of the groups of Schlesinger transformations of their associated linear problems. These groups admit a very natural lattice structure. Each Schlesinger transformation induces a B\"acklund transformation of the -Painlev\'e equation. Each translational B\"acklund transformation may be lifted to the level of the associated linear problem, effectively showing that each translational B\"acklund transformation admits a Lax pair. We will demonstrate this framework for the -Painlev\'e equations up to and including -.
