For a given θ ∈ (a, b), we investigate the question whether there exists a positive quadrature formula with maximal degree of precision which has the prescribed abscissa θ plus possibly a and/or b, the endpoints of the interval of integration. This study relies on recent results on the location of roots of quasi-orthogonal polynomials. The above positive(More)

This paper is an introductory approach to several approximation problems of periodic functions in connection with Fourier series, Lipschitz functions and related topics. Traditional results in this context are presented and discussed in the first two sections. Further, we introduce certain Hölder spaces of integrable functions that become homogeneous Banach(More)
