[图书][B] Orthogonal polynomials for exponential weights

E Levin, DS Lubinsky - 2001 - Springer
The analysis of orthogonal polynomials associated with general weights was a major theme
in classical analysis in the twentieth century, and undoubtedly will continue to grow in …

Multiple orthogonal polynomials

AI Aptekarev - Journal of Computational and Applied Mathematics, 1998 - Elsevier
Results on multiple orthogonal polynomials will be surveyed. Multiple orthogonal
polynomials are intimately related to Hermite-Padé approximants and often they are also …

[图书][B] Weighted approximation with varying weight

V Totik - 2006 - books.google.com
A new construction is given for approximating a logarithmic potential by a discrete one. This
yields a new approach to approximation with weighted polynomials of the form w" n"("" …

Relative asymptotics for polynomials orthogonal with respect to a discrete Sobolev inner product

G López, F Marcellán, W Van Assche - Constructive Approximation, 1995 - Springer
We investigate the asymptotic properties of orthogonal polynomials for a class of inner
products including the discrete Sobolev inner products\left ⟨ h, g\right ⟩= ∫ hgd μ+ ∑ _ j …

Strong asymptotics of multiply orthogonal polynomials for Nikishin systems

AI Aptekarev - Sbornik: Mathematics, 1999 - iopscience.iop.org
Strong asymptotic formulae for the Hermite-Padé polynomials for systems of Markov-type
functions in the Nikishin class are obtained. The proof is based on the properties of certain …

Quadrature formulas based on rational interpolation

W Van Assche, I Vanherwegen - mathematics of computation, 1993 - ams.org
We consider quadrature formulas based on interpolation using the basis functions
$1/(1+{t_k} x)\quad (k= 1, 2, 3,\ldots) $ on $[-1, 1] $, where ${t_k} $ are parameters on the …

Ratio and relative asymptotics of polynomials orthogonal on an arc of the unit circle

MB Hernández, GL Lagomasino - Journal of approximation theory, 1998 - Elsevier
Ratio and relative asymptotics are given for sequences of polynomials orthogonal with
respect to measures supported on an arc of the unit circle, where their absolutely continuous …

Asymptotics of orthogonal polynomials: some old, some new, some identities

DS Lubinsky - Acta Applicandae Mathematica, 2000 - Springer
We briefly review some asymptotics of orthonormal polynomials. Then we derive the
Bernstein–Szegő, the Riemann–Hilbert (or Fokas–Its–Kitaev), and Rakhmanov projection …

[PDF][PDF] Convergence of rational interpolants

H Stahl - Bulletin of the Belgian Mathematical Society Simon …, 1996 - math.ethz.ch
The convergence of (diagonal) sequences of rational interpolants to an analytic function is
investigated. Problems connected with their definition are shortly discussed. Results about …
