　　In this paper,we proposed a local discontinuous Petrov-Galerkin method for the generalized Burgers-Huxley equation and the generalized BurgersFisher equation.The stability analysis of the method is derived for two special cases.The method can choose different trial and test function spaces and preserve the advantage of discontinuous finite element method.Furthermore,the method is easier to accomplished since its computational formula is simpler than the local discontinuous Galerkin method when t...
