Multipoint Padé Approximations of the Beta Function
A. A. Kandayan M. V. Lomonosov Moscow State University, Faculty of Mechanics and Mathematics
Abstract:
We study multipoint rational approximations with free poles for the beta function. The denominators of the approximations satisfy orthogonality relations with variable weight with respect to a discrete measure. We obtain the limit distribution of zeros of the denominators. A potential-theoretic interpretation of the results obtained is given.
Keywords:
beta function, Padé approximation, logarithmic potential theory, Rakhmanov's equilibrium problem, Rodrigues' formula, Cauchy transform.
