An interesting class of submanifolds of a Kahler manifold M2n is the class of submanifolds Nn ⊑ M2n which are minimal with respect to the metric on M2n and are Lagrangian with respect to the symplectic form on M2n. A general Kahler manifold will not have any of these submanifolds. However, in this paper, we show that if the metric on M2n is also Einstein, then these minimal Lagrangian submanifolds exist in abundance, at least locally. We give a precise description of this "generality" in terms of Cartan-Kahler theory and relate these submanifolds to the calibrated geometries of Harvey and Lawson and to maximal real structures on algebraic varieties.
