We propose two preconditioners based on the fast sine transformation for solving linear systems with ill-conditioned multilevel Toeplitz structure. These matrices are generated by discretizing the two-dimensional nonlocal Helmholtz equations with fractional Laplacian operators via the finite difference method. For complex wave numbers with nonnegat...
