Abstract:
Dual $p$-adic multiresolution analyses (MRAs) generated by scaling test functions are studied. It is proved that if two MRAs are dual, then each of MRAs is the Haar MRA. A characterization of all biorthogonal wavelet systems associated with the Haar MRA is given for the case $p=2$.
Key words and phrases:$p$-adic multiresolution analysis, scaling function, Riesz basis, $p$-adic wavelets.
