Asymptotics of Hermite-Padé Polynomials and Related Convergence Results — A Summary of Resultspes have identical asymptotics. It turns out that a certain determinantal condition is necessary and sufficient for the identical asymptotics. The asymptotic distributions of the zeros of the polynomials as vell as the domains of convergence for the three types of approximants are characterized by certain logarithmic potentials.

On the Behavior of Zeros and Poles of Best Uniform Polynomial and Rational Approximantsmial approximants distribute like the equilibrium measure for E. In contrast, we show that there might be another subsequence with zeros essentially all tending to ∞. Also, we investigate near best approximants. For rational best approximants we prove that its zeros and poles cannot all stay outside a neighborhood of E, unless f is analytic on E.

Multipoint Padé Approximation and Orthogonal Rational Functions), and assume that Φ(R.) ≠ 0 when R(t) ≢ 0. The Gram-Schmidt process applied to the sequence . gives an orthogonal system {Q. (z)} of functions in .. These orthogonal functions can be used to construct multipoint Padé approximants for the given series.

Once Again: The Adamjan-Arov-Krein Approximation Theory such a Hankel matrix is related simply to its serial number. Unlike the classical proofs, which are notoriously sophisticated, the pure matrix proof we outline here is both reasonably simple and transparent.

Minimal Pade-Sense Matrix Approximations Around , = 0 and , = ∞paper. Our main tool is the construction of a nested basis for the null spaces of block Hankel matrices. The proof of the algorithm and other aspects of the minimal partial realization can be found in . We only give the main result.
