---|---|---|
In this paper, a new approach in the estimation of weighted integrals of periodic functions on unbounded intervals of the
real line is presented by considering an associated weight function on the unit circle and making use of both Szegő and interpolatory
type quadrature formulas. Upper bounds for the estimation of the error are considered along with some examples and applications
related to the Rogers-Szegő polynomials, the evaluation of the Weierstrass operator, the Poisson kernel and certain strong
Stieltjes weight functions. Several numerical experiments are finally carried out. |
