mit dem Thema:

"The Nordstrom-Vlasov system"

Abstract:
The Nordstrom-Vlasov system describes the dynamics of a self-gravitating
ensemble of collision less particles in the framework of a relativistic
scalar theory of gravitation. Although this is not a physically correct
model, it is interesting
because it still captures some of the essential features which distinguish
the non-relativistic model, the Vlasov-Poisson system, from the correct
relativistic model, the Einstein-Vlasov system. Examples of such features
are the non-linearity of the field equation and the propagation of
gravitational waves due to the hyperbolic character of the system. In this
talk I will give a short introduction to the Nordstrom-Vlasov system and
present some results concerning the existence of classical solutions and of
spherically symmetric equilibria with finite radius.
