The Vlasov-Poisson equation, the Moebius Geometry and then-body problem in a negative space form

الأصل · EN

By using, the Vlasov-Poisson equation defined in either a Riemannian or a semi-Riemannian space Rᵏg, and a Dirac distribution function, we re-obtain the well known and classical equations of motion of a mechanical system with a pairwise acting potential function. We apply this result to the study of an n--body problem in a two dimensional negative space form with the hyperbolic cotangent potential. Following the Klein's geometric Erlangen program, with methods of Möbius geometry and using the Iwasawa decomposition of the Möbius isometric group SL(2,R) via its representation in one Clifford Algebra, we complete the study of the whole set of Möbius solutions (relative equilibria) of the problem begun by Diacu et al. in Diacu8.
