Progress\, however\, has largely been focused on questions at t he kinematical or phenomenological level\, since no robust dynamical mecha nism for their formation has yet been established. This is a central issue \, as the viability of regular black holes ultimately depends on such dyna mical considerations. In this talk\, I will argue that\, if regular black holes play a role in resolving spacetime singularities\, they may arise na turally from resummed higher-derivative corrections of the kind expected i n quantum gravity. I will discuss a recent explicit realization of this id ea\, survey the main results obtained so far in this framework\, and highl ight the major open problems that remain.

Regular\, singulari ty-free black holes have been studied for more than sixty years as a possi ble resolution of the black hole singularity problem. Progress\, however\, has largely been focused on questions at the kinematical or phenomenologi cal level\, since no robust dynamical mechanism for their formation has ye t 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 resummed higher-derivative corrections of the kind expected in quantum gravity.

I will discuss a recent explicit realization of this idea\, survey the main results obtained so far in this framework\, and highlight the ma jor open problems that remain.
