Two-Scale Macro-Micro decomposition of the Vlasov equation
with a strong magnetic field

ABSTRACT

 

A two-scale macro-micro decomposition of the Vlasov equation consists in writing the solution of the equation as a sum of two oscillating functions with circumscribed oscillations. The first of these functions is close in some sense to the two-scale limit of the solution and the second one is a correction built to offset this limit. The aim of such a decomposition is to be the starting point for the construction of two-scale asymptotic-preserving schemes.
