The Lower Estimate for Bernstein Operator [PDF]

open access: yes, 2013
MSC 2010: 41A10, 41A15, 41A25, 41A36For functions belonging to the classes C2[0; 1] and C3[0; 1], we establish the lower estimate with an explicit constant in approximation by Bernstein polynomials in terms of the second order Ditzian-Totik modulus of ...

The Lebesgue Constant for the Periodic Franklin System

open access: yes, 2011
We identify the torus with the unit interval $[0,1)$ and let $n,\nu\in\mathbb{N}$, $1\leq \nu\leq n-1$ and $N:=n+\nu$. Then we define the (partially equally spaced) knots \[ t_{j}=\{[c]{ll}% \frac{j}{2n}, & \text{for}j=0,...,2\nu, \frac{j-\nu}{n ...

Elliptic scaling functions as compactly supported multivariate analogs of the B-splines [PDF]

open access: yes, 2013
In the paper, we present a family of multivariate compactly supported scaling functions, which we call as elliptic scaling functions. The elliptic scaling functions are the convolution of elliptic splines, which correspond to homogeneous elliptic ...

Generalized splines in ℝn and optimal control [PDF]

open access: yes, 2006
We give a new time-dependent definition of spline curves in ℝn, which extends a recent definition of vector-valued splines introduced by Rodrigues and Silva Leite for the time-independent case.

Addendum to : Orthonormal bases of regular wavelets in spaces of homogeneous type

open access: yes, 2015
We bring a precision to our cited work concerning the notion of "Borel measures", as the choice among different existing definitions impacts on the validity of the results.Comment: 1 page.

Complete graphs: the space of simplicial cones, and their path tree representation

open access: yes, 2017
Let $G$ be a complete graph with $n+1$ vertices. In a recent paper of the authors, it is shown that the path trees of the graph play a special role in the structure of the truncated powers and partition functions that are associated with the graph ...

Univariate spline quasi-interpolants and applications to numerical analysis

open access: yes, 2005
We describe some new univariate spline quasi-interpolants on uniform partitions of bounded intervals. Then we give some applications to numerical analysis: integration, differentiation and approximation of ...
