The \(q\)-discrete Painlevé IV equations and their properties
The authors study in detail the properties of two \(q\)-discrete Painlevé IV equations: singularity structure, bilinear forms, auto-Backlund/Schlesinger transformations, rational solutions as well as special solutions obtained through second- or first-order linear equations.
