On Best Approximation By Rational And Holomorphic Mappings Between Banach Spaces
, 2015 After proving a generalized version of Garkavi's theorem, we give as applications proofs of existence results on best approximation by polynomials, and fractional linear and holomorphic operators between Banach spaces.

Artificial molecular machines and motors—Design and control of nanoscale motion
FEBS Letters, EarlyView.Molecules are constantly moving because of thermal fluctuations, but random motion alone cannot be exploited to perform directional tasks. Artificial molecular machines use chemical, electrical, or light energy to bias this motion. Molecular shuttles, rotary motors, and supramolecular pumps illustrate how nanoscale movement can be controlled and ...

On rational approximation in a ball in ℂN
International Journal of Mathematics and Mathematical Sciences, 2000 We study rational approximations of elements of a special class of meromorphic functions which are characterized by their holomorphic behavior near the origin in balls in ℂN by means of their rational approximants. We examine two modes of convergence for

Mathematical and Computational Applications, 2018 A complete MAPLE procedure is designed to effectively implement an algorithm for approximating trigonometric functions. The algorithm gives a piecewise polynomial approximation on an arbitrary interval, presenting a special partition that we can get its ...

APPROXIMATION BY SEVERAL RATIONALS [PDF]
Bulletin of the Australian Mathematical Society, 2008 AbstractFollowing T. H. Chan, we consider the problem of approximation of a given rational fraction a/q by sums of several rational fractions a1/q1,…,an/qn with smaller denominators. We show that in the special cases of n=3 and n=4 and certain admissible ranges for the denominators q1,…,qn, one can improve a result of T. H.

The elliptic functions and integrals of the "1/9" problem
, 2000 We describe the functions needed in the determination of the rate of convergence of best L-infinity rational approximation to exp(-x) on [0,infinity) when the degree n of the approximation tends to infinity ("1/9" problem)
