摘要：
Properties of the nonlinear Schrodinger equation, a form that often arises in many-body problems, are investigated. The eigenvalues for a diffuse boson gas confined in a sphere are evaluated. The important differences from the linear case, such as the nonorthogonality of the eigenfunctions and their dramatically different variational properties are examined.
