A Type of Multigrid Method Based on the Fixed-Shift Inverse Iteration for the Steklov Eigenvalue Problem

الملخص EN

For the Steklov eigenvalue problem, we establish a type of multigrid discretizations based on the fixed-shift inverse iteration and study in depth its a priori/a posteriori error estimates.

In addition, we also propose an adaptive algorithm on the basis of the a posteriori error estimates.

Finally, we present some numerical examples to validate the efficiency of our method.
