Bianchi I ``asymptotically Kasner'' solutions of the Einstein scalar field equations

نویسندگان

چکیده

In this work we investigate the asymptotic behaviour of solutions to Einstein equations with a minimally coupled scalar field. The primary focus present paper here establishing under what conditions solution becomes "asymptotically Kasner" sufficiently close initial singularity. To address question restrict our attention Bianchi I space-times. By restricting strictly monotonic field are able provide necessary on potential so that resulting is asymptotically Kasner. Moreover, both explicit and numerical examples Kasner

Exact solutions of classical scalar field equations

We give a class of exact solutions of quartic scalar field theories. These solutions prove to be interesting as are characterized by the production of mass contributions arising from the nonlinear terms while maintaining a wavelike behavior. So, a quartic massless equation has a nonlinear wave solution with a dispersion relation of a massive wave and a quartic scalar theory gets its mass term r...

The Initial Singularity in Solutions of the Einstein-vlasov System of Bianchi Type I

The dynamics of solutions of the Einstein-Vlasov system with Bianchi I symmetry is discussed in the case of massive or massless particles. It is shown that in the case of massive particles the solutions are asymptotic to isotropic dust solutions at late times. The initial singularity is more diicult to analyse. It is shown that the asymptotic behaviour there must be one of a small set of possib...

Dynamics of the spatially homogeneous Bianchi type I Einstein-Vlasov equations

We investigate the dynamics of spatially homogeneous solutions of the EinsteinVlasov equations with Bianchi type I symmetry by using dynamical systems methods. All models are forever expanding and isotropize toward the future; toward the past there exists a singularity. We identify and describe all possible past asymptotic states; in particular, on the past attractor set we establish the existe...

The dynamical stability of the static real scalar field solutions to the Einstein-Klein-Gordon equations revisited

We re-examine the dynamical stability of the nakedly singular, static, spherically symmetric solutions of the Einstein-Klein Gordon system. We correct an earlier proof of the instability of these solutions, and demonstrate that there are solutions to the massive Klein-Gordon system that are perturbatively stable.

Asymptotically Simple Solutions of the Vacuum Einstein Equations in Even Dimensions

We show that a set of conformally invariant equations derived from the Fefferman-Graham tensor can be used to construct global solutions of vacuum Einstein equations, in all even dimensions. This gives, in particular, a new, simple proof of Friedrich’s result on the future hyperboloidal stability of Minkowski spacetime, and extends its validity to even dimensions.
