Progress\, however\, has largely been focused on questions at the kinematical or phenomenological level\, since no robust dynamical mech anism for their formation has yet been established. This is a central issu e\, as the viability of regular black holes ultimately depends on such dyn amical considerations. In this talk\, I will argue that\, if regular black holes play a role in resolving spacetime singularities\, they may arise n aturally from resummed higher-derivative corrections of the kind expected in quantum gravity. I will discuss a recent explicit realization of this i dea\, survey the main results obtained so far in this framework\, and high light the major open problems that remain.

Regular\, singular ity-free black holes have been studied for more than sixty years as a poss ible resolution of the black hole singularity problem. Progress\, however\ , has largely been focused on questions at the kinematical or phenomenolog ical level\, since no robust dynamical mechanism for their formation has y et been established. This is a central issue\, as the viability of regular black holes ultimately depends on such dynamical considerations.

In this talk\, I will argue that\, if regular black holes play a role in resolving spacetime singularities\, they may arise naturally from resumme d higher-derivative corrections of the kind expected in quantum gravity. < br/>
I will discuss a recent explicit realization of this idea\, surve y the main results obtained so far in this framework\, and highlight the m ajor open problems that remain.
