CHEBYSHEV RATIONAL APPROXIMATION TO ENTIRE FUNCTIONS IN [ 0 , oc ]
Introduction : Quite recently Chebyshev rational approximation to certain entire functions on the whole positive axis has attracted the attention of many mathematicians. In this respect the papers ([3-7, 9]) are worth mentioning. All these papers have been devoted only to entire functions of finite order. On the other hand, methods developed and used in these papers are valid only to entire fun...
متن کاملCertain Hilbert Spaces of Entire Functions
1. Introduction. The research reported on in the present note was motivated by the following Proposition (F), due to Ernest Fischer ([5], see also [4] for an earlier version; actually Fischer proved a more general result, but the special case suffices as a point of departure for our discussion) : (F) Let P denote a homogeneous polynomial in si, • • • , z k with complex coefficients. Then every ...
متن کاملNumerical approximations for population growth model by Rational Chebyshev and Hermite Functions collocation approach: A comparison
This paper aims to compare rational Chebyshev (RC) and Hermite functions (HF) collocation approach to solve the Volterra’s model for population growth of a species within a closed system. This model is a nonlinear integro-differential equation where the integral term represents the effect of toxin. This approach is based on orthogonal functions which will be defined. The collocation method redu...
متن کاملRational Chebyshev Approximations for Fermi-Dirac Integrals of Orders
Rational Chebyshev approximations are given for the complete Fermi-Dirac integrals of orders — \, \ and f. Maximal relative errors vary with the function and interval considered, but generally range down to 10~9 or less.
متن کاملEntire Functions That Share Rational Functions with Their Derivatives
In this paper, we use the idea of normal family to deal with the uniqueness problems of entire functions that share a rational function with its derivative and get a uniqueness theorem. The conclusions in this paper can be used to improve several known results. Some examples are provided to show that the results presented in this paper are possible. AMS Mathematics Subject Classification (2010)...
