On Hamiltonian stationary Lagrangian spheres in non-Einstein Kaehler surfaces

Ildefonso Castro, Francisco Torralbo, Francisco Urbano

Hamiltonian stationary Lagrangian spheres in Kaehler-Einstein surfaces are minimal. We prove that in the family of non-Einstein Kaehler surfaces given by the product ${\Sigma }_1\times {\Sigma }_2$…
