Scattered Node Compact Finite Difference-Type Formulas Generated from Radial Basis Functions
In standard equispaced finite difference (FD) formulas, symmetries can make the order of accuracy relatively high compared to the number of nodes in the FD stencil. With scattered nodes, such symmetries are no longer available.

A characterization of multivariate dual wavelet tight frames for any general dilation matrix is presented in this paper. As an application, Lawton's result on wavelet tight frames in L (IR) is generalized to the n-dimensional case.

Approximation From Shift-Invariant Subspaces of ...
: A complete characterization is given of closed shift-invariant subspaces of L 2 (IR d ) which provide a specified approximation order. When such a space is principal (i.e., generated by a single function), then this characterization is in terms of ...

On Existence and Weak Stability of Matrix Refinable Functions
: We consider the existence of distributional (or L 2 ) solutions of the matrix refinement equation b \Phi = P(\Delta=2) b \Phi(\Delta=2); where P is an r \Theta r matrix with trigonometric polynomial entries.
