On a lower bound for the rate of convergence of multipoint Padé approximants of piecewise analytic functions
V. I. Buslaev Steklov Mathematical Institute of Russian Academy of Sciences, Moscow
Abstract:
We obtain a lower bound for the rate of convergence of multipoint Padé approximants of functions holomorphically
extendable from a compact set to a union of domains whose boundaries possess a symmetry property. The
bound obtained matches a known upper bound for the same quantity.
Keywords:
rational approximation, orthogonal polynomials, Padé approximants, distribution of poles, convergence in capacity.
