On Chebyshev-type integral quasi-interpolation operators

Mathematics and Computers in Simulation, 2009
The article deals with quasi-interpolants of a function \(f\), \[ Qf = \sum_{i \in \mathbb Z} \lambda f (\cdot + i) \phi(\cdot - i), \] where \(\phi\) is a certain piecewise polynomial partition of unity with a compact support, and where \(\lambda\) is a linear functional of the form \[ \lambda f=\sum_{j \in J} \gamma_j \langle f , \psi(\cdot + j ...

Cubature of Integral Operators by Approximate Quasi-interpolation

2009
In this paper we report on some recent results concerning Hermite quasi-interpolation on uniform grids with interesting applications to the approximation of solutions to elliptic PDE, quasi-interpolation on nonuniform grids and the cubature of convolutions with radial kernel functions based on an approximation method proposed by V. Maz’ya.

A new multiquadric quasi‐interpolation operator with interpolation property

Mathematical Methods in the Applied Sciences, 2013
In this article, we discuss a class of multiquadric quasi‐interpolation operator that is primarily on the basis of Wu–Schaback's quasi‐interpolation operator and radial basis function interpolation. The proposed operator possesses the advantages of linear polynomial reproducing property, interpolation property, and high accuracy.
