Query: Crystallographic Multiwavelets in $L^2(R^d)$   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 necessary and sufficient conditions in terms of the
symbol matrix in order that an associated crystal wavelet basis exists.
