Simultaneous Rational Approximation to Binomial Functions
We apply Padé approximation techniques to deduce lower bounds for simultaneous rational approximation to one or more algebraic numbers. In particular, we strengthen work of Osgood, Fel’dman and Rickert, proving, for example, that max {∣∣∣√2− p1/q∣∣∣ , ∣∣∣√3− p2/q∣∣∣} > q−1.79155 for q > q0 (where the latter is an effective constant). Some of the Diophantine consequences of such bounds will be d...
متن کاملOn Uniform Approximation of Rational Perturbations of Cauchy Integrals
Let [c, d] be an interval on the real line and μ be a measure of the form dμ = μ̇dω[c,d] with μ̇ = h~, where ~(t) = (t − c)c(d − t)d , αc, αd ∈ [0, 1/2), h is a Dini-continuous non-vanishing function on [c, d] with an argument of bounded variation, and ω[c,d] is the normalized arcsine distribution on [c, d]. Further, let p and q be two polynomials such that deg(p) < deg(q) and [c, d] ∩ z(q) = ∅, ...
متن کاملRational Minimax Approximation via Adaptive Barycentric Representations
Computing rational minimax approximations can be very challenging when there are singularities on or near the interval of approximation — precisely the case where rational functions outperform polynomials by a landslide. We show that far more robust algorithms than previously available can be developed by making use of rational barycentric representations whose support points are chosen in an a...
متن کاملRational Transform Approximation via the Laguerre Spectrum
In t roduc t ion An important class of functions from the point of view of signal representation and approximation is the class with n th order rational Laplace transforms. These functions arise naturally in such fields as model identification and timedomain synthesis. The problem of finding the best n th order rational function to represent a given time function is, therefore, important; unfor...
متن کاملBest Simultaneous Approximation on Small Regions by Rational Functions
We study the behavior of best simultaneous (lq , Lp)-approximation by rational functions on an interval, when the measure tends to zero. In addition, we consider the case of polynomial approximation on a finite union of intervals. We also get an interpolation result.
