Abstract

In this thesis we investigate the existence and properties of stationary solutions of the flat Vlasov-Poisson system. This system of partial differential equations can be used as a model of extremely flat astronomical objects and is a combination between the two-dimensional motion of particles and the three-dimensional interaction through their gravitational potential.

Abstract in another language

In dieser Dissertation beschäftige ich mich mit dem flachen Vlasov-Poisson-System, einem System partieller Differentialgleichungen, welches als Modell für hinreichend flache astronomische Objekte weithin in Gebrauch ist. Im Zentrum der Arbeit steht die Entwicklung einer Existenztheorie für speziell geartete stationäre Lösungen dieses Systems und die Untersuchung deren weiterer Eigenschaften. Die wesentliche Schwierigkeit bei der flachen Variante des Vlasov-Poisson-Systems besteht in der Kopplung von zweidimensionaler Teilchenbewegung und ´dreidimensionaler Wechselwirkung´ durch gravitative Kräfte.
