Abstract

We present a class of regular axisymmetric black hole geometries fully characterized by the parameters {ℳ,a} and possessing the Kerr event horizon. This family interpolates between regular spacetimes, configurations with integrable singularities, and the Kerr solution as a limiting case. Its main features are: (i) the existence of quasi-extremal configurations without requiring a ≈ ℳ; and (ii) a possible framework toward an analytical description of Kerr black hole formation from an initially regular configuration.
