Abstract
In this paper, we establish a positive lower bound estimate for the second smallest eigenvalue of the complex Hessian of solutions to a degenerate complex Monge–Ampère equation. As a consequence, we find that in the space of Kähler potentials any two points close to each other in \(C^2\) norm can be connected by a geodesic along which the associated metrics do not degenerate.
