Abstract

In this paper, we present the results of the numerical evolution of scalar field solitons in asymptotically flat space–times. First we introduce the model we are working with and then we briefly mention the complications that arise in this particular numerical simulation, presenting some details of code we used and some examples of the results.

Keywords: Numerical relativity; classical black holes and solitons.

Resumen

En este artículo, presentamos los resultados de la evolución numérica de solitones de campo escalar en espacios–tiempos asintóticamente planos. En primer lugar introducimos el modelo con el que estamos trabajando y posteriormente mencionamos las complicaciones que surgen en esta simulación numérica, mostrando algunos detalles del código y ejemplos de los resultados.

Descriptores: Relatividad numérica; agujeros negros clásicos y solitones.
