Özet
The Cauchy problem for abstract telegraph equations d(2)u(t)/dt(2) + alpha du(t)/dt + Au(t) + beta u(t) = f (t) (0 <= t <= T), u(0) = phi, u'(0) = psi in a Hilbert space H with the self-adjoint positive definite operator A is studied. Stability estimates for the solution of this problem are established. The first and second order of accuracy difference schemes for the approximate solution of this problem are presented. Stability estimates for the solution of these difference schemes are established. In applications, two mixed problems for telegraph partial differential equations are investigated. The methods are illustrated by numerical examples.
