Szukana fraza: [Abstract = "This work is devoted to the numerical simulation of the Vlasov equation using a phase space grid. In contrast to Particle\-In\-Cell \(PIC\) methods, which are known to be noisy, we propose a semi\-Lagrangian\-type method to discretize the Vlasov equation in the two\-dimensional phase space. As this kind of method requires a huge computational effort, one has to carry out the simulations on parallel machines."]
