报告摘要:In this talk, I will introduce our works on extensions of two semi-discrete integrable systems and further discuss their relations to orthogonal polynomials. First, we extend the Schur flow to a nonisospectral case and find its a Lax pair expressed in terms of the orthogonal polynomials on the unit circle. Then, we extend the molecule solution of the hungry Lotka-Volterra lattice to nonzero boundaries and present its relation to a set of symmetric (M,1)-biorthogonal polynomials. Our results are obtained by Hirota’s bilinear method and determinant techniques.
