Correspondence theorems for infinite Hopf-Galois extensions

Hoan-Phung Bui, Joost Vercruysse, Gabor Wiese

This paper extends Hopf-Galois theory to infinite field extensions and provides a natural definition of subextensions. For separable (possibly infinite) Hopf-Galois extensions, it…

Wavelet frame bijectivity on Lebesgue and Hardy spaces

H. -Q. Bui, R. S. Laugesen

We prove a sufficient condition for frame-type wavelet series in $L^{p}$ , the Hardy space $H^{1}$ , and BMO. For example, functions in these spaces are shown to have expansions in terms…

A note on the solution of the Mexican hat problem

H. -Q. Bui, R. S. Laugesen

We prove a technical estimate needed in our recent solution of the completeness question for the non-orthogonal Mexican hat wavelet system, in $L^{p}$ for $1 < p < 2$ and in the Hardy sp…
