| Abstract: | In the application field of space physics, nuclear physics, laser and electronic technology, there are many Helmholtz equations and Modified Helmholtz equation associated with the boundary value problem. However, the targeted researches on the issues are rare at present. By using the methods from complex equation, this paper studies a class of Riemann-Hilbert boudary value problems for Modified Helmholtz equation and discusses its solvability and uniqueness in different cases. The theorems of solvability of the problems are obtained. In addition, this paper studies the oblique derivative boundary value problems for the Modified Helmholtz equation of second order on the unit disk by using the preceding results. |
