On second order of accuracy difference scheme of the approximate solution of nonlocal elliptic-parabolic problems (Q1957592)

Summary: A second order of accuracy difference scheme for the approximate solution of the abstract nonlocal boundary value problem \( - d^{2}u(t)/dt^{2}+Au(t)=g(t), (0\leq t\leq 1), du(t)/dt - Au(t)=f(t), ( - 1\leq t\leq 0), u(1)=u( - 1)+\mu \) 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.
