Solvability of Vekua-type periodic operators and applications to classical equations

Abstract

In this note, we investigate Vekua-type periodic operators of the form $Pu=Lu-Au-B\bar{u}$, where $L$ is a constant coefficient partial differential operator. We provide a complete characterization of the necessary and sufficient conditions for the solvability and global hypoellipticity of $P$. As an application, we provide a comprehensive characterization of Vekua-type operators associated with classical wave, heat, and Laplace equations.
