Solitary Waves of the Vlasov–Poisson System Masahiro Suzuki (Nagoya Institute of Technology)
Abstract
We consider the Vlasov--Poisson system describing a two-species plasma with spatial dimension 1 and the velocity variable in . We find the necessary and sufficient conditions for the existence of solitary waves of the system. To this end, we need to investigate the distribution of ions trapped by the electrostatic potential. Furthermore, we classify completely in all possible cases whether or not the solitary wave is unique, when we exclude the variant caused by translation. There are both cases that it is unique and nonunique.
