Abstract

In 1993, Y.-G. Oh proposed a problem whether standard Lagrangian tori in Cn are volume minimizing under Hamiltonian isotopies of Cn. In this article, we prove that most of them do not have such property if the dimension n is greater than two. We also discuss the existence of Hamiltonian non-volume minimizing Lagrangian torus orbits of compact toric Kahler manifolds.
