A rigorous stability result for the Vlasov-Poisson system in three dimensions. (English) Zbl 0791.49030
Summary: It is proven that in a neutral two-component plasma with space homogeneous positively charged background, which is governed by the Vlasov-Poisson system and for which Poisson’s equation is considered on a cube in $${\mathbf R}^ 3$$ with periodic boundary conditions, the space homogeneous stationary solutions $$g$$ with energy gradient $$\partial g/\partial\varepsilon\leq 0$$ and compact support are (nonlinearly) stable in the $$L^ 1$$-norm with respect to weak solutions of the initial value problem.
