Abstract

In this article, we present a characterization of nonuniform multiwavelets associated to a nonuniform multiresolution analysis (NUMRA) having finite multiplicity in terms of its dimension function. This, in turn, improves the main result of Gabardo and Yu given in (J Math Anal Appl 323(2):798–817, 2006). The concept of NUMRA was introduced by Gabardo and Nashed in which the translation set is a spectrum that is no longer a group.
