Abstract
This paper considers an initial-boundary value problem for a linear multidimensional first-order differential-algebraic system of index (1, 0). For its numerical solution, a four-point three-layer locally one-dimensional difference scheme is used. It is proven that, under certain conditions on the steps of the difference grid, such a scheme is stable in terms of the initial-boundary conditions and in the right-hand side. The results of numerical experiments are presented.
