2. 1. On the Einstein-Vlasov system

   Author : Mikael Fjällborg; Alexander Bobylev; Markus Kunze; Karlstads universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Einstein-Vlasov system; finite extension; monotone functions; MATHEMATICS; MATEMATIK; Matematik; Mathematics;

   Abstract : In this thesis we consider the Einstein-Vlasov system, which models a system of particles within the framework of general relativity, and where collisions between the particles are assumed to be sufficiently rare to be neglected. Here the particles are stars, galaxies or even clusters of galaxies, which interact by the gravitational field generated collectively by the particles. READ MORE

4. 2. On the Einstein-Vlasov system: Stationary Solutions and Small Data Solutions with Charged and Massless Particles

   Author : Maximilian Thaller; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Static Solutions; Vector Field Method; non-linear wave equation; massless Einstein-Vlasov system; General Relativity; Conformal Einstein Field Equations; Minkowski stability; Vlasov matter; symmetric hyperbolic system; Einstein-Vlasov-Maxwell system;

   Abstract : The Vlasov matter model describes an ensemble of collisionless particles moving through space-time. These particles interact via the gravitational field which they create collectively. In the framework of General Relativity this gravitational field is described by space-time curvature. READ MORE

5. 3. On the cylindrically symmetric Einstein-Vlasov system

   Author : Mikael Fjällborg; []
   Keywords : ;

   Abstract : For the cylindrically symmetric ''asymptotically flat'' Einstein equations in the case of electro-vacuum it is known that solutions exist globally and even that this class of spacetimes are causally geodesically complete. Hence the strong cosmic censorship holds for this class. READ MORE

6. 4. Compact Relativistic Matter Shells with Massless and Charged Particles

   Author : Maximilian Thaller; Göteborgs universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Spherical Symmetry; massless Einstein-Vlasov system; Einstein-Vlasov-Maxwell system; Static Solutions; Vlasov matter; General Relativity; Einstein-Vlasov-Maxwell system;

   Abstract : The Vlasov model is a matter model that is widely used in physics. In the context of astrophysics and cosmology it describes an ensemble of self gravitating, collisionless particles. These particles can be interpreted as for example ions, stars, or galaxies. READ MORE
