Although the above analysis of the algebraic multilevel method is limited to the diagonally dominant SPD case, the method is actually applicable to a much wider class of problems. Indeed, it is applied below to off-diagonally dominant problems such as diffusion problems with oblique anisotropy, the Maxwell equations, and the highly nonsymmetric convection diffusion equation.
