Nonisospectral deformations of noncommutative Laurent biorthogonal polynomials and matrix discrete Painlevé-type equations
Dan Dai, Xiaolu Yue
In this paper, we establishes a connection between noncommutative Laurent biorthogonal polynomials (bi-OPs) and matrix discrete Painlevé (dP) equations. We first apply nonisospect…

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-…
