Near best refinable quasi-interpolants
Mathematics and Computers in Simulation, 2009Let \(\mathbb{Z}\) be the set of integers and \(n\geq2\) be fixed. The authors consider the class of linearly independent refinable functions \[ M_{n,h}:=\left\{ m_{n,h}(\cdot-k),k\in\mathbb{Z}\right\} , \] where \(m_{n,h}(x)\) has support \(\left[ -n,n\right] ,\) is centered at the origin and satisfies the refinement equation: \[ m_{n,h}(x)=\sum_{k=n}^

Quasi-Interpolation on Irregular Points
1994A quasi-interpolant is an operator L having the form $$Lf = \sum\limits_{i = 1}^\infty {f\left( {{y_i}} \right){g_i}} .$$ (1.1) The points y i are called “nodes”; they are prescribed in ℝ n . The entities g i are prescribed functions from ℝ n to ℝ. The case of irregularly situated nodes is of particular interest.

Quasi-Interpolation on Compact Domains
1995Quasi-interpolation schemes are often based on the construction of an approximation to the identity on some discrete set of points. Such schemes generally fail on compact regions because evaluation of the approximate identity on the boundary of the region requires function evaluations outside the region.
