Late-time tails of self-gravitating skyrmions

Autor: Zajac, Stanislaw

Publikováno v: Acta Phys.Polon.B42:249,2011

We consider the long-time behaviour of spherically symmetric solutions in the Einstein-Skyrme model. Using nonlinear perturbation analysis we obtain the leading order estimation of the tail in the topologically trivial sector (B = 0) of the model. We

Late-time tails of wave maps coupled to gravity

We consider the late-time asymptotic behavior for solutions of Einstein's equations with the wave map matter. Solutions starting from small compactly supported $\ell$-equivariant initial data with $\ell\geq 1$ are shown to decay as $t^{-(2\ell+2)}$ a
