Approximation with Riemann-Liouville fractional derivatives

, 2019
In this article we study quantitatively with rates the pointwise con-vergence of a sequence of positive sublinear operators to the unit operator over continuous functions.

Q-deformed and λ-parametrized A-generalized logistic function induced Banach space valued multivariate multi-layer neural network approximations

Here we research the multivariate quantitative approximation of Banach space valued continuous multivariate functions on a box or RN, N ∈ N, by the multivariate normalized, quasi-interpolation, Kantorovich type and quadrature type neural network ...

Weighted Approximation by the Goodman–Sharma-Type Operators

, 2012
P. E. Parvanov - The uniform weighted approximation errors of the Goodman–Sharma operators are characterized for functions.Равномерната теглова апроксимация с модифицирани по Гудман–Шарма опера-тори от тип на Бернщайн, Баскаков и Майер–Кьоних–Целер е ...

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.
