Quadrature formulas associated with RogersSzeg? polynomials
This paper is concerned with the estimation of integrals of 2? 2 ? -periodic functions with respect to the Hermite weight function by passing to the unit circle of the complex plane and considering Szeg? and interpolatory-type quadrature formulas with respect now to the RogersSzeg? weight function. Several numerical experiments are given along with estimations of the error.
