【Abstract】 This paper proposes a new method-the space-time finite element method for parabolic equations. The results of numerical experiments and its comparison with the semi-discrete Galerkin method show that the space-time finite element method has better accuracy and stability and is more economical and efficient than the semi-discrete Galerkin method.更多还原
