摘要
In this paper) we shall give two new variational formulations for Wilson element on arbitraryquadrilateral meshes. It is shown that the convergence order is O(h) as the Wilson element withoriginal variational formulation. Furthermore, the multigrid method of the Wilson element withthe two new variational formulations is developed, and the order of convergence is also O(h).
