KW - Mortar $P_1$ nonconforming element, Cascadic multigrid method.
AB - <p style="text-align: justify;">In this paper, we consider the cascadic multigrid method for the mortar $P_1$ nonconforming element which is used to solve the Poisson equation and prove that the cascadic conjugate gradient method is accurate with optimal complexity. &nbsp;</p>
