Özet

The initial-value problem for hyperbolic equation d(2)u(t)/dt(2) + A(t) u(t) = f (t) (0 <= t <= T), u(0) =phi, u' (0) = psi in a Hilbert space H with the self-adjoint positive definite operators A(t) is considered. The second order of accuracy difference scheme for the approximately solving this initial-value problem is presented. The stability estimates for the solution of this difference scheme are established. Copyright (c) 2007 A. Ashyralyev and M. E. Koksal.
