We prove that symplectic maps between Riemann surfaces L, M of constant, nonpositive curvature converge to minimal symplectic maps, if the Lagrangian angle for the corresponding Lagrangian submanifold in the cross product space satisfies . If one considers a 4-dimensional Kähler-Einstein manifold of nonpositive scalar curvature that admits two complex structures J, K which commute and assumes that is a compact oriented Lagrangian submanifold w.r.t. J such that the Kähler form w.r.t. K restricted to L is positive, then L converges under the mean curvature flow to a minimal Lagrangian submanifold which is calibrated w.r.t. .
