Extended Newman-Janis algorithm for rotating and Kerr-Newman de Sitter and anti de Sitter metrics

Autor: de Urreta, E. J. Gonzalez, Socolovsky, M.

The Newman-Janis algorithm is well known to provide rotating black holes solutions to Einstein's equations from static seeds, through a complexification of a radial and a time coordinates. However, an ambiguity remains for the replacement of the $r^{
