Abstract: This paper gives an overview of recent achievements of the
multiwavelet theory. The construction of multiwavelets is based on a
multiresolution analysis with higher multiplicity generated by a scaling vector.
The basic properties of scaling vectors such as L^2-stability, approximation
order and regularity are studied. Most of the proofs are sketched.
Keywords: multiwavelets, L^2-stability, approximation order, regularity, scaling vectors
