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