Algorithms based on bilinear finite elements for iterative methods with split boundary conditions for a Stokes-type system in a strip under the periodicity condition. (Q1975080)

In this paper the algorithms are developed, based on approximating both velocities and pressure by bilinear finite elements, for all iterative (which were constructed earlier) processes with completely and incompletely split boundary conditions. These algorithms are designed for the Dirichlet problem for a two-dimensional singularly perturbed Stokes-type system on a strip when the solutions to this problem are periodic in the direction of the boundary.
