These problems have been motivated by some previous work by J. J. Guadalupe et al. when the standard orthogonality using measures with mass points is considered in the study of Fourier expansions in terms of orthogonal polynomials.application/pdfspaSobolev type orthogonal polynomialsFourier seriesFourier projectorsEstimatesconference paperMatemáticasopen access
