Abstract
This paper is concerned with the finite volume element methods on quadrilateral mesh for second-order elliptic equation with variable coefficients. An error estimate in L 2 norm is shown on the quadrilateral meshes consisting of h 2-parallelograms. Superconvergence of numerical solution is also derived in an average gradient norm on h 2-uniform quadrilateral meshes. Numerical examples confirm our theoretical conclusions.
