Authors: ANTONIO L. BAISÓN OLMO, VÍCTOR A. CRUZ BARRIGUETE, JAIME NAVARRO

Abstract: The continuous wavelet transform in higher dimensions is used to prove the regularity of weak solutions $u \in L^p(\mathbb R^n)$ under $Qu = f$ where $f$ belongs to the Triebel-Lizorkin space $F^{r,q}_p(\mathbb R^n)$ where $1 < p,q < \infty$, $0< r <1$, and where $Q = \sum_{\vert \beta\vert \leq m} c_{\beta}{\partial^{\beta}}$ is a linear partial differential operator of order $m >0$ with positive constant coefficients $c_{\beta}$.

Keywords: Admissible function, continuous wavelet transform, Triebel-Lizorkin spaces, weak solution, regularity, differential operators
