Abstract: In one-dimensional case implicit monotone finite difference schemes are proposed to approximate gas dynamics problems. It is proved that a solution to FDEs exists and is unique. The schemes proposed can be extended to many-dimensional case. Numerical solution of some gas dynamics problems is demonstrated.
