Abstract:
Hamiltonian stationary Lagrangian submanifolds are critical points of the volume of Lagrangian
submanifolds under variations in the form $J Df$ in a symplectic manifold with a Riemannian metric
compatible with an almost complex structure $J$ and the symplectic structure. We prove a C^1 regular
Hamiltonian stationary Lagrangian submanifold in a symplectic manifold is smooth. We achieve this by
developing an elliptic theory for a class of fourthorder equations in the double divergence form. This is
joint work with A. Bhattacharya and M. Warren.
