Аннотация

In this paper we analyse an approximation of linear nonstationary convection-diffusion problem based on combination of discontinues Galerkin method for time discretisa-tion in conjunction with hybridized discontinues Galerkin for spatial approximation. Such dis-crete schemes can be used for the solution of equations degenerating in the leading part and are formulated in term of solution of the problem, its gradient, the diffusional flux, and the re-striction of the solution to the boundaries of elements. Conditions responsible for the solvabil-ity, stability and accuracy of the schemes are presented.
