Stationary Galerkin method for a parabolic equation with changing time direction. (Russian) Zbl 1274.35202
Summary: We apply a stationary Galerkin method for solving the first boundary problem for a parabolic equation with changing time direction in a cylindrical domain. We choose the basis functions as the solutions of the spectral problem for the Laplace equation. We study the weak and strong convergence of the approximate solutions to a regular solution.
