Abstract: This paper is devoted to multgrid methods for solving the quad-curl eigenvalue problem. The multgrid methods based on the Rayleigh quotient iteration and the inverse iteration with fixed shift are proposed. We prove the error estimates for both methods. Numerical experiments confirm our theoretical analysis and validate the efficiency of both methods.
