Abstract: A first order of accuracy difference scheme for the approximate solution of abstract nonlocal boundary value problem −d2u(t)/dt2 + sign(t)Au(t) = g(t), (0 ≤ t ≤ 1), du(t)/dt + sign(t)Au(t) = f(t), (−1 ≤ t ≤ 0), u(0+) = u(0−), u′(0+) = u′(0−),and 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 without a weight is established. Moreover, as applications, coercivity estimates in Hölder norms for the solutions of nonlocal boundary value problems for elliptic‐parabolic equations are obtained.
