Abstract
Mixed finite element method is developed to approximate the solution of the initial-boundary value problem for a strongly nonlinear second-order hyperbolic equation in divergence form. Existence and uniqueness of the approximation are proved, and optimal-orderL ∞-in-time,L 2-in-space a priori error estimates are derived for both the scalar and vector functions approximated by the method.
