On a nonhomogeneous heat equation on the complex plane

Abstract

In this article, we investigate the existence, uniqueness, and asymptotic behaviors of mild solutions of a parabolic evolution equations on complex plane, in which the diffusion operator has the form \(\overline{\Box}_φ = \overline{D}\, \overline{D}^{\ast}\), where \(\overline{D} f = \bar{\partial}f + φ_{\bar{z}} f\), the function \(φ\) is smooth and subharmonic on \(\mathbb{C}\), and \(\overline{D}^{\ast}\) is the formal adjoint of \(\overline{D}\). Our method combines certain estimates of heat kernel associating with the homogeneous linear equation of Raich \cite{raich06} and a fixed point argument.
