Quantitative uniform approximation by generalized discrete singular operators

, 2015
Here we study the approximation properties with rates of generalized discrete versions of Picard, Gauss-Weierstrass, and Poisson-Cauchy singular op- erators. We treat both the unitary and non-unitary cases of the operators above.

Stability of Multiscale Transformations

, 1996
After briefly reviewing the interrelation between Riesz-bases, biorthogonality and a certain stability notion for multiscale basis transformations we establish a basic stability criterion for a general Hilbert space setting.

Degree of Simultaneous Coconvex Polynomial Approximation

, 1998
: Let f 2 C 1 [\Gamma1; 1] change its convexity finitely many times in the interval, say s times, at Y s : \Gamma1 ! y s ! \Delta \Delta \Delta ! y 1 ! 1.
