Stationary reduction method based on nonisospectral deformation of orthogonal polynomials, and discrete Painlevé-type equations

Xiao-Lu Yue, Xiang-Ke Chang, Xing-Biao Hu

In this work, we propose a new approach called ``stationary reduction method based on nonisospectral deformation of orthogonal polynomials" for deriving discrete Painlevé-type (d-…
