Recursion Relation for Toeplitz Determinants and the Discrete Painlevé II Hierarchy
Solutions of the discrete Painlevé II hierarchy are shown to be in relation to a family of Toeplitz determinants describing certain quantities in multicritical random partition models, for which the limiting behavior has been recently considered in the literature. Our proof is based on the Riemann-H...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Резюме: | Solutions of the discrete Painlevé II hierarchy are shown to be in relation to a family of Toeplitz determinants describing certain quantities in multicritical random partition models, for which the limiting behavior has been recently considered in the literature. Our proof is based on the Riemann-Hilbert approach for the orthogonal polynomials on the unit circle related to the Toeplitz determinants of interest. This technique allows us to construct a new Lax pair for the discrete Painlevé II hierarchy that is then mapped to the one introduced by Cresswell and Joshi.
