Given a minimal Lagrangian submanifold L in a negative Kähler–Einstein manifold M, we show that any small Kähler–Einstein perturbation of M induces a deformation of L which is minimal Lagrangian with respect to the new structure. This provides a new source of examples of minimal Lagrangians. More generally, the same is true for the larger class of totally real J-minimal submanifolds in Kähler manifolds with negative definite Ricci curvature.

Abstract
Given a minimal Lagrangian submanifold L in a negative Kähler–Einstein manifold M, we show that any small Kähler–Einstein perturbation of M induces a deformation of L which is minimal Lagrangian with respect to the new structure. This provides a new source of examples of minimal Lagrangians. More generally, the same is true for the larger class of totally real J-minimal submanifolds in Kähler manifolds with negative definite Ricci curvature.
