A Posteriori Error Estimates for Mixed Finite Element Galerkin Approximations to Second Order Linear Hyperbolic Equations
In this article, a posteriori error analysis for mixed finite element Galerkin approximations of second order linear hyperbolic equations is discussed. Based on mixed elliptic reconstructions and an integration tool, which is a variation of Baker’s technique introduced earlier by G. Baker (SIAM J. Numer. Anal., 13 (1976), 564-576) in the context of a priori estimates for a second order wave equ...

On the Correct Formulation of a Multidimensional Problem for Strictly Hyperbolic Equations of Higher Order
A theorem of the unique solvability of the first boundary value problem in the Sobolev weighted spaces is proved for higherorder strictly hyperbolic systems in the conic domain with special orientation. In the space Rn, n > 2, let us consider a strictly hyperbolic equation of the form p(x, ∂)u(x) = f(x), (1) where ∂ = (∂1, . . . , ∂n), ∂j = ∂/∂xj , p(x, ξ) is a real polynomial of order 2m, m > ...
متن کاملThe Cauchy Problem for Nonlinear Hyperbolic Equations of Higher order using Modified Decomposition Method
In this paper modified decomposition method is applied to the solvability of nonlinear hyperbolic equations of higher order with initial conditions and illustrated with a few simple examples. The results obtained indicate that Modified Decomposition Method is very effective and simple.
