Abstract

We study $L^2$ and Sobolev estimates for solutions of the Cauchy–Riemann equation on pseudoconvex and pseudoconcave domains in $\mathbb{CP}^n$. We also formulate the weak and strong extensions of the $\overline{\partial}$ equation in Sobolev spaces and study their dual problems.

Keywords
