Polynomial Difference Schemes with Energy and Momentum Multipliers on Orthogonal Uniform Meshes: Stencil Restrictions and Monge--Ampère-Type Examples

E. I. Kaptsov

Experience with invariant finite-difference schemes for one-dimensional hydro\-dynamic-type equations for a function suggests that nonlinear polynomial schemes on orthogon…

Symmetry-Preserving Finite-Difference Schemes and Auto-Bäcklund Transformations for the Schwarz Equation

E. I. Kaptsov, V. A. Dorodnitsyn

It is demonstrated that one of the equations from the Lie classification list of second-order ODEs is a first integral of the Schwarz equation. As symmetry-preserving finite-differ…

Symmetries and conservation laws of the one-dimensional shallow water magnetohydrodynamics equations in Lagrangian coordinates

S. V. Meleshko, V. A. Dorodnitsyn, E. I. Kaptsov

Symmetries of the one-dimensional shallow water magnetohydrodynamics equations (SMHD) in Gilman's approximation are studied. The SMHD equations are considered in case of a plane an…
