N-point Padé approximants and two-sided estimates of errors on the real axis for Stieltjes functions
Publikováno v:
Journal of Computational and Applied Mathematics. 178:247-253
Upper and lower estimates of Stieltjes function by N-point Padé approximants can be obtained using the new general inequality reported by Tokarzewski et al. (Arch. Mech. 54 (2002) 141–153) and rigorously proved in the present paper. In addition, w

The reliability of rational approximations built from noisy data is explored. One considers a rational interpolation f(t) of a function S(t) known only via its, randomly perturbed, values at a finite number of real points. It is found that in the sma

The analytic structure of Rational Interpolants (R.I.) f (z) built from randomly perturbed data is explored; the interpolation nodes x j , j = 1,...,M, are real points where the function f reaches these prescribed data $$\widetilde\phi _j$$ . It is a

We continue a study of Pade approximants (PA) for a series perturbed by random noise – this time we consider more general rational functions. We begin with the simple case of a sum of two geometric series, and then show how these considerations can

We consider the roots of two families of polynomials which can be derived as the characteristic polynomials of some (generalized) transfer matrices. We study the possible multiplicities and the number of real roots. Moreover, the number of roots lyin

A theoretical analysis of the concept of lifetime and mean life of unstable elementary particles is presented. New analytic formulas for lifetime and mean life as a function of decay width Γ and the mass of unstable particle are derived for Breit-Wi
