Description
The celebrated works by Penrose and Hawking established that black holes in general relativity are inevitably doomed to contain singularities in their interiors. This is no longer the case for regular black holes, for which no singularities appear. Recently, it has been shown that the Schwarzschild singularity may be resolved after the addition of an infinite tower of higher-curvature corrections to the Einstein-Hilbert action. Nevertheless, this explicit construction only works for space-time dimensions larger or equal than five. In this talk, I will explain how regular black holes from pure gravity may also be built in four dimensions, present along the way two mechanisms for their dynamical formation. This talk will be mainly based on Phys.Rev.D 113 (2026) 2, 024019.
