About positive, energy conservative and equilibrium state preserving schemes for the isotropic Fokker-Planck-Landau equation
... In this section we propose a new derivation of this method which intrinsically contains the conservation of the energy. We recall also the scheme developed by Langdon et al. [15, 24], but in the case where potentials are ...

Construction of a blow-up solution for the Complex Ginzburg-Landau equation in some critical case
... For our purpose, we consider CGL independently from any particular physical context and investigate it as a mathematical model in partial differential equations with p > 1. We note also that the interest on the study ...

Positive, conservative, equilibrium state preserving and implicit difference schemes for the isotropic Fokker-Planck-Landau equation
... Time discretization is also a crucial point in the numerical simulation of the Fokker-Planck- Landau equation. Implicit schemes are attractive: they make the code robust and able to use large time steps ...
