Dilaton gravity black holes with regular interior
arXiv:gr-qc/9708017 · doi:10.1103/PhysRevD.57.6185
Abstract
In a one parameter family of dilaton gravity theories which allow the coupling of the dilaton to gravity and to a U(1) gauge field to differ, we have found the existence of everywhere regular spacetimes describing black holes hiding expanding universes inside their horizon.
