Abstract:
Given a compact Lagrangian submanifold in flat space evolving by its mean curvature, we prove uniform formula4-bounds in space and formula6-estimates in time for the underlying Monge-Ampère 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.
