Recurrence relations for the coefficients of expansions in classical orthogonal polynomials of a discrete variable
Paweł Woźny (2003)
Applicationes Mathematicae
A method is given to find a recurrence relation for the coefficients of the series expansion of a function f with respect to classical orthogonal polynomials of a discrete variable, which follows from a linear difference equation satisfied by f.
Recurrences for the coefficients of series expansions with respect to classical orthogonal polynomials
Stanislaw Lewanowicz (2002)
Applicationes Mathematicae
Let be any sequence of classical orthogonal polynomials. Further, let f be a function satisfying a linear differential equation with polynomial coefficients. We give an algorithm to construct, in a compact form, a recurrence relation satisfied by the coefficients in . A systematic use of the basic properties (including some nonstandard ones) of the polynomials results in obtaining a low order of the recurrence.

Results on spline-Fourier and Ciesielski-Fourier series
Ferenc Weisz (2006)
Banach Center Publications
Some recent results on spline-Fourier and Ciesielski-Fourier series are summarized. The convergence of spline Fourier series and the basis properties of the spline systems are considered. Some classical topics, that are well known for trigonometric and Walsh-Fourier series, are investigated for Ciesielski-Fourier series, such as inequalities for the Fourier coefficients, convergence a.e. and in norm, Fejér and θ-summability, strong summability and multipliers. The connection between Fourier series...

Riesz transforms for the Dunkl Ornstein-Uhlenbeck operator
Adam Nowak, Luz Roncal, Krzysztof Stempak (2010)
Colloquium Mathematicae
We propose a definition of Riesz transforms associated to the Ornstein-Uhlenbeck operator based on the Dunkl Laplacian. In the case related to the group ℤ ₂ it is proved that the Riesz transform is bounded on the corresponding spaces, 1 < p < ∞.
