Abstract

We construct spherically symmetric, static solutions to the Einstein-Vlasov system with non-vanishing cosmological constant Λ\Lambda. The results are divided as follows. For small Λ>0\Lambda>0 we show existence of globally regular solutions which coincide with the Schwarzschild-deSitter solution in the exterior of the matter sources. For Λ<0\Lambda<0 we show via an energy estimate the existence of globally regular solutions which coincide with the Schwarzschild-Anti-deSitter solution in the exterior vacuum region. We also construct solutions with a Schwarzschild singularity at the center regardless of the sign of Λ\Lambda. For all solutions considered, the energy density and the pressure components have bounded support. Finally, we point out a straightforward method to obtain a large class of globally non-vacuum spacetimes with topologies R×S3\mathbb R\times S^3 and R×S2×R\mathbb R\times S^2\times \mathbb R which arise from our solutions using the periodicity of the Schwarzschild-deSitter solution. A subclass of these solutions contains black holes of different masses.
