Multiresolution weighted norm equivalences and applications

We establish multiresolution norm equivalences in
weighted spaces <i>L<sup>2</sup><sub>w</sub></i>((0,1))
with possibly singular weight functions <i>w(x)</i>&ge;0
in (0,1).
Our analysis exploits the locality of the
biorthogonal wavelet basis and its dual basis
functions. The discrete norms are sums of wavelet
coefficients which are weighted with respect to the
collocated weight function <i>w(x)</i> within each scale.
Since norm equivalences for Sobolev norms are by now
well-known, our result can also be applied to
weighted Sobolev norms. We apply our theory to
the problem of preconditioning <i>p</i>-Version FEM
and wavelet discretizations of degenerate
elliptic problems.
