Convergence of Fourier sums by polynomials orthogonal on arbitrary lattice
A. A. Nurmagomedov Chair of Mathematical Disciplines in Economics, M. M. Dzhambulatov Dagestan State Agricultural Academy, Makhachkala, Russia
Abstract:
We study approximation properties of discrete Fourier sums of a function on the segment $[-1,1]$ on an orthonormal system of polynomials representing finite-difference analogs of classical Legendre polynomials. In particular, we find an order of the norm of discrete Fourier sum.
Keywords:
polynomial, orthogonal system, lattice, weight, weight estimate, asymptotic formula, approximation, Fourier sums.
