On approximation by Chebyshevian box splines

Zygmunt Wronicz (2002)

Annales Polonici Mathematici

Chebyshevian box splines were introduced in [5]. The purpose of this paper is to show some new properties of them in the case when the weight functions $w_{j}$ are of the form $w_{j} (x) = W_{j} (v_{n + j} \cdot x)$ , where the functions $W_{j}$ are periodic functions of one variable. Then we consider the problem of approximation of continuous functions by Chebyshevian box splines.

We give a generalization of box splines. We prove some of their properties and we give applications to interpolation and approximation of functions.

On the boundedness of the mapping $f \to | f |$ in Besov spaces

Patrick Oswald (1992)

Commentationes Mathematicae Universitatis Carolinae

For $1 \leq p \leq \infty$ , precise conditions on the parameters are given under which the particular superposition operator $T : f \to | f |$ is a bounded map in the Besov space $B_{p, q}^{s} (R^{1})$ . The proofs rely on linear spline approximation theory.
