On convergence of discrete methods of least squares on equidistant nodes
René Goertz
We consider the well-known method of least squares on an equidistant grid with nodes on the interval with the goal to approximate a function $f\in\mathcal{C}\left[-1…

On Hahn polynomial expansion of a continuous function of bounded variation
René Goertz, Philipp Öffner
We consider the well-known method of least squares on an equidistant grid with nodes on the interval . We investigate the following problem: For which ratio and…

Spectral accuracy for the Hahn polynomials
René Goertz, Philipp Öffner
We consider in this paper the Hahn polynomials and their application in numerical methods. The Hahn polynomials are classical discrete orthogonal polynomials. We analyse the behavi…
