On conservative and entropic discrete axisymmetric Fokker-Planck operators
On conservative and entropic discrete axisymmetric Fokker-Planck operators
We study, in axisymmetnc geometry, a discretization of the Fokker-Planck operator that preserves the physical properties which are decrease of the kinetic entropy and conservation of mass, momentum and energy and only those quantifies For this purpose, we exhibit how the above properties are conséquences, first, of the algebraic structure …
