DESCRIPTION:Speakers: Breno Loureiro Giacchini (Charles University)\nHighe
 r-derivative and nonlocal gravity models arise in various approaches to qu
 antum gravity\, either as candidates for renormalizable theories of gravit
 y or as effective low-energy descriptions. In this talk\, we present sever
 al recent results on classical solutions in higher-derivative gravity\, fo
 cusing on the possibility of resolving the black-hole singularity present 
 in solutions of general relativity and quadratic gravity. We discuss the f
 irst local classification of static\, spherically symmetric exact solution
 s in generic six-derivative gravity and in a quasi-local extension of Eins
 tein-Weyl gravity. Although only regular cores are found in both cases\, w
 e argue that more complicated singular solutions might still exist and dis
 cuss the possibility of having regular black holes in these models.\n[Base
