A second order of accuracy difference scheme for the approximate solution of the abstract nonlocal boundary value problem d2u(t)/dt2+Au(t)=g(t), (0t1), du(t)/dtAu(t)=f(t), (1t0), u(1)=u(1)+μ for differential equations in a Hilbert space H with a self-adjoint positive definite operator A is considered. The well posedness of this difference scheme in Hölder spaces is established. In applications, coercivity inequalities for the solution of a difference scheme for elliptic-parabolic equations are obtained and a numerical example is presented.
