An integrable chain and bi-orthogonal polynomials
The authors investigate self-similar solutions to the equations of motion of the integrable chain connected to the isospectral evolution of the polynomials of type \(R-I\) introduced by Ismail and Masson before. The polynomials of these equations are expressed in terms of the Gauss hypergeometric function and are shown to be stable against Darboux transformations of the generalized chain.
