Abstract:

A theory of mixed finite element approximations of a class of linear self-adjoint boundary-value problems is developed which involves splitting a problem of the type TTu f into a pair of canonical equations, Tu v, TV f. Consistency and stability of finite-elementGalerkin approximations of the pair described, convergence criteria are established, and error estimates are derived for a number of important cases.
