A q-analog of the sixth Painlevé equation

M Jimbo, H Sakai - Letters in Mathematical Physics, 1996 - Springer
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 …

On the extension of the Painlevé property to difference equations

MJ Ablowitz, R Halburd, B Herbst - Nonlinearity, 2000 - iopscience.iop.org
It is well known that the integrability (solvability) of a differential equation is related to the
singularity structure of its solutions in the complex domain-an observation that lies behind …
