Abstract

In this work we show that spherically symmetric regular black holes with topologies other than S³ de Sitter cores cannot be excluded from Borde's theorem. In particular, we prove that spacetime connectivity leads to an S³ core by discarding other allowed topologies, such as the orientable and non orientable S² bundles over S¹, for achronal slices. Finally, some conjectures regarding physical quantification of topology change in these spacetimes are discussed.
