Minimal Lagrangian isotropic immersions in indefinite complex space forms

Let MnMn be an nn-dimensional (n≥3n≥3) minimal Lagrangian isotropic submanifold in an indefinite complex space form. We show that the dimension of MnMn satisfies n=3r+2n=3r+2 with rr, a positive integer. When n<14n<14, we give a classification of such submanifolds.
