On extending the Painlev\'e test to the one-dimensional Vlasov equation
Abstract
An analysis of possible extension of the Painlev\'e test, to encompass the one-dimensional Vlasov equation, is performed. The extending requires a nontrivial generalization of the test. The proposed singularity analysis provides classification of the solutions possessing the Painlev\'e property by the order and number of pole surfaces. The compatibility conditions for the Laurent series have the form of an overdetermined system of 1st order differential equations, which themselves need a compatibility condition. This eventually leads to constraints which implicitly yield a family of solutions. The complete calculation is provided for the case of one simple order pole. The solutions describe evolution of plasmas in a uniform electric field.

Minute corrections in the number of equations and the requirements for the initial condition. The main solution remains unaltered
