In this paper, we use a semi-discrete and a padΓ© approximation method to propose a new difference scheme for solving convection-diffusion problems. The truncation error of the difference scheme is O(h 4 + Ο 5 ). It is shown through analysis that the scheme is unconditionally stable. Numerical experi
We prove two new criteria for the sufficiency of the von Neumann condition for stability of difference schemes. The first criterion is that the von Neumann criterion is sufficient for stability if a finite power of the amplification matrix is a uniformly diagonalizable matrix. The second criterion r
