　　This talk presents a weak Galerkin(WG)finite element method for the Cahn-Hilliard equation.The WG method makes use of piecewise polynomials as approximating functions,with weakly partial derivatives(first and second order)computed locally by using the information in the interior and on the boundary of each element.
