Abstract.

Given a compact Lagrangian submanifold in flat space evolving by its mean curvature, we prove uniform \(C^{2,\alpha}\)-bounds in space and C 2-estimates in time for the underlying Monge-Ampére equation under weak and natural assumptions on the initial Lagrangian submanifold. This implies longtime existence and convergence of the Lagrangian mean curvature flow. In the 2-dimensional case we can relax our assumptions and obtain two independent proofs for the same result.
