【Abstract】 The case with a nonlinear perturbation term of Dirac operator was discussed.The connection between the nonlinear eigenvalue problem and the linear eigenvalue problem was established through constructing a continuous mapping.The existence of eigenvalues of perturbated operator and its eigenfunctions were proved by using the fixed point theorem.更多还原
