Bernstein-Riemann interpolation formula for arbitrary continuous functions on a segment

In this paper, we obtain an interpolation formula for arbitrary continuous functions on the interval [0,1], with known values of these functions on some uniform grid. No additional assumptions about functions are required. The construction of such a formula is connected with the properties of local Bernstein polynomials and the Riemann zeta function. Numerical results of interpolation of functions of the Riemann, Weierstrass, Bizikovich and Takagi type are presented.

Abstract

In this paper, we obtain an interpolation formula for arbitrary continuous functions on the interval [0,1], with known values of these functions on some uniform grid. No additional assumptions about functions are required. The construction of such a formula is connected with the properties of local Bernstein polynomials and the Riemann zeta function. Numerical results of interpolation of functions of the Riemann, Weierstrass, Bizikovich and Takagi type are presented.
