Abstract
Classic mixed and regularized variational formulations are considered in the paper for a complex vector Helmholtz equation. A comparative analysis is presented for these formulations and solvability issues are discussed. Preconditioned formulations of problems proposed here can be used for further solution of finite element analogues of continuous problems by iterative methods in Krylov’s subspaces.
