Open AccessHyperbolic Wavelet Analysis of Classical Isotropic and Anisotropic Besov–Sobolev Spaces
In this paper we introduce new function spaces which we call anisotropic hyperbolic Besov and Triebel-Lizorkin spaces. Their definition is based on a hyperbolic Littlewood-Paley analysis involving an anisotrop...

Wavelet Bases for Confinements of the Infrared Divergence
We propose the construction of wavelet bases with pseudo-polynomials adapted to the homogeneous Sobolev spaces $\dot{H}^{s}(\mathbb{R...
