Rotating non-singular black holes — •Roman Smit and Piero Nicolini — Frankfurt Institute for Advanced Studies (FIAS), Frankfurt am Main, Germany

A variety of non-singular spherically symmetric black hole solutions have been found in the past. Their energy momentum tensor is usually an anisotropic perfect fluid with a dark-energy-like equation of state (p=-ρ) for the radial pressure.

Historically, the Kerr-Newman solution was found by applying a complexification algorithm -- the Newman-Janis algorithm -- to the Reissner-Nordstroem solution.

I will show how to modify and apply this algorithm to the known spherical non-singular black holes to obtain rotating non-singular black holes.
