Approximation by crystal-refinable function

Ursula Molter, Maria del Carmen Moure, Alejandro Quintero

Let $Γ$ be a crystal group in $R^{d}$ . A function $φ : R^{d} ⟶ C$ is said to be {\em crystal-refinable} (or $Γ -$ refinable) if it is a linear combinat…

Crystallographic Multiwavelets in $L^{2} (R^{d})$

Ursula Molter, Alejandro Quintero

We characterize the scaling function of a crystal Multiresolution Analysis in terms of the vector-scaling function for a Multiresolution Analysis associated to a lattice. We give n…
