A quadratic finite element wavelet Riesz basis
Νικόλαος Ρεκατσίνας, Rob P. Stevenson · International Journal of Wavelets Multiresolution and Information Processing · 2018
In this paper, continuous piecewise quadratic finite element wavelets are constructed on general polygons in [Formula: see text]. The wavelets are stable in [Formula: see text] for [Formula: see text] and have two vanishing moments. Each wavelet is a linear combination of 11 or 13 nodal basis functions. Numerically computed condition numbers for [Formula: see text] are provided for the unit square.
