报告摘要Let L be a compact oriented Lagrangian surface in a Kahler surface with a complete metric with bounded sectional curvature and positive injectivity radius lower bound. We show that for  each closed curve c in L which is not contractible in L but bounds a disk in M there is a holomorphic disk in M with boundary in L representing the homotopy class c.
