Minimal and H-minimal submanifolds in toric geometry

In this paper we investigate a family of Hamiltonian-minimal Lagrangian submanifolds in C-m, CPm and other symplectic toric manifolds constructed from intersections of real quadrics. In particular we explain the nature of this phenomenon by proving H-minimality in a more conceptual way, and prove minimality of the same submanifolds in the corresponding moment-angle manifolds.
