Estimates for the convergence rate of a Fourier series in Laguerre-Sobolev polynomials
In a Sobolev type space with weight \(e^{-x}\), the Fourier series are considered in polynomials orthogonal in Sobolev's sense and generated by the classical Laguerre polynomials. In the study of approximation by the corresponding partial sums a rate of convergence is obtained.
