Preconditioners for multilevel Toeplitz linear systems from steady-state and evolutionary advection-diffusion equations

In this paper, we study preconditioners for multilevel Toeplitz linear systems arising from discretization of steady-state and evolutionary advection-diffusion equations, in which upwind scheme and central difference scheme are employed to discretize first-order and second-order terms, respectively....
