Stability and error estimates are established for the finite element method to solve a class of second order hyperbolic equations.Meanwhile,optimal rates of convergence in H 1 and L 2 norm are obtained.
The finite element methods for the mathematic model of one kind of ion reactions for the problem of groundwater are considered. We use a standard Galerkin method for the ion concentrations. Optimal error estimates in ...
We consider general problems of Mathematical finance and the associated Hamilton Jacobi Bellman equations. The mixed finite element is used. The semidiscrete and the fulldiscrete finite element approximation are consi...
