Solution to a semilinear pseudoparabolic problem with integral conditions. (English) Zbl 1112.35115

Summary: In this article, we use the Rothe time-discretization method to prove the well-posedness of a mixed problem with integral conditions for a third order semilinear pseudoparabolic equation. Also we establish the convergence of the method and an error estimate for a semi-discrete approximation.
