Outline of Final Research Achievements

On this research theme, I have obtained the following results: (1) the finiteness and infiniteness theorems of discrete spectrum of the Schrodinger operators on noncompact manifolds, (2) the existence and uniqueness theorems of the Dirichlet problem at infinity for harmonic maps between asymptotic hyperbolic manifolds, (3) the representational formula and halfspace theorem for minimal Legendrian surfaces in the 5-dimensional Heisenberg group, (4) the value distribution theorem for the Gauss maps of minimal Lagrangian surfaces in the complex 2-space.
