Extension of a Function from the Exterior of an Interval to a Positive-Definite Function on the Entire Axis and an Approximation Characteristic of the Class $W_M^{r, β}$

Abstract

We establish sufficient conditions for the extension of a function defined on

$[a, +∞)$ , where

$a > 0$ , to a positive-definite function on the entire axis.
