On the Structure and Interpolation Properties of Quasi Shift-invariant Spaces

Keaton Hamm, Jeff Ledford

The structure of certain types of quasi shift-invariant spaces, which take the form $V (ψ, X) := span^{L_{2}} {ψ (\cdot - x_{j}) : j \in Z}$ for a discrete s…

Regular Families of Kernels for Nonlinear Approximation

Keaton Hamm, Jeff Ledford

This article studies sufficient conditions on families of approximating kernels which provide $N$ --term approximation errors from an associated nonlinear approximation space which…

Nonuniform Sampling and Recovery of Bandlimited Functions in Higher Dimensions

Keaton Hamm

We provide sufficient conditions on a family of functions $(ϕ_{α})_{α \in A} : R^{d} \to R$ for sampling of multivariate bandlimited functions at certain nonuniform sequen…

Approximation Rates for Interpolation of Sobolev Functions via Gaussians and Allied Functions

Keaton Hamm

A \Riesz-basis sequence for $L_{2} [- π, π]$ is a strictly increasing sequence $X := (x_{j})_{j \in Z}$ in $R$ such that the set of functions $\left(e^{-ix_j(\cdot)}\right)_…
