Abstract:

A one dimension fourthorder finite volume element method based on the LobattoGauss was constructured. The author analysed the stability and convergence of this method, proved the superconvergence of numerical derivatives at the dual partition nodes. The numerical experiments verified the super\|convergence of the method.

Key words: twopoint boundary value problem, finite volume element method, error estimate, superconvergence
