The log-concavity of eigenfunction to complex Monge-Ampère operator in ${\mathbb{C}}^2$

Abstract

Following the authors' recent work \cite{Zhang-Zhou2025}, we further explore the convexity properties of solutions to the Dirichlet problem for the complex Monge-Ampère operator. In this paper, we establish the $\log$-concavity of solutions to the Dirichlet eigenvalue problem for the complex Monge-Ampère operator on bounded, smooth, strictly convex domain in ${\mathbb{C}}^2$. Our approach combines a constant rank theorem adapted to the study of real convexity in the complex setting with a deformation method.
