摘要：
The paper deals with studying some preconditioning operators which provide uncoditional convergence of difference schemes for solving parabolic problems. Three examples of such operators are considered. These are a preconditioner of the domain decomposition method of the Neumann-Dirichlet type and two preconditioners of the fictitious domain methods for the Neumann and the Dirichlet boundary value problems, respectively.
