Overiteration of d-variate tensor product Bernstein operators: A quantitative result (Dedicated to the memory of Professor Sorin Gal)

Extending an earlier estimate for the degree of approximation of over iterated univariate Bernstein operators towards the same operator of degree one, it is shown that an analogous result holds in the d-variate case.

Global smoothness preservation and simultaneous approximation by multivariate discrete operators: Dedicated to Professor Gheorghe Coman on the occasion of his 80th anniversary

, 2016
In this article we study the multivariate generalized discrete singular operators defined on R N , N ≥ 1, regarding their simultaneus global smoothness preservation property with respect to Lp norm for 1 ≤ p ≤ ∞, by using higher order moduli of ...

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.
