Bäcklund transforms of the extreme Kerr near-horizon geometry

arXiv:1909.06104 · doi:10.1016/j.physleta.2020.126572

Abstract

We apply the method of Bäcklund transformations to generate a new hierarchy of exact solutions to the vacuum Einstein equations starting from the extreme Kerr near-horizon geometry. Solutions with extreme Kerr near-horizon asymptotics containing an arbitrary number of free parameters are included.
