About convergence of difference schemes for a third-order pseudo-parabolic equation with nonlocal boundary value condition

Abstract

A nonlocal boundary value problem for a third-order pseudoparabolic equation with variable coecients is considered. For solving this problem, a priori estimates in the dierential and dierence forms are obtained. The obtained a priori estimates imply the uniqueness and stability of the solution on a layer with respect to the initial data and the right-hand side and the convergence of the solution of the dierence problem to the solution of the dierential problem.
