Title: On global solutions for the Vlasov-Poisson system Author: Peter Zhidkov (Joint Institute for Nuclear Research, Dubna, Russia) Abstract: In this article we show that the Vlasov-Poisson system has a unique weak solution in the space $L_1\cap L_\infty$. For this purpose, we use the method of characteristics, unlike the approach in [12]. Submitted February 13, 2004. Published April 14, 2004. Math Subject Classifications: 35Q72, 82C05, 82C40.
