This work shows that the method of charcteristics is well suited for the numerical solution of first order hyperbolic partial differential equations whose coefficients are approximated by functions piecewise constant on a finite element triangulation of the domain of integration. We apply this method to the numerical solution of Euler's equation and prove convergence when the time step and the ...

— We introducé two a posteriori error estimators for piecewise îinear nonconforming finit e element approximation of second order e Hipt ie problems. We prove that these estimators are equivalent to the energy norm of the error, Finally, we present several numerical experiments showing the good behavior of the estimators when they are used as local error indicators for adaptive refinement. Résu...
