Non-abelian Yang-Mills in Kundt spacetimes

Abstract

We present new exact solutions of the Einstein-Yang-Mills system. The solutions are described by a null Yang-Mills field in a Kundt spacetime. They generalize a previously known solution for a metric of $pp$ wave type. The solutions are formally of Petrov type III.Comment: Talk presented at the XXVIII Spanish Relativity Meeting E.R.E. 2005, Oviedo, September 6-10, 2005, to be published by AIP Conference Proceedings, 5 page
