Claims

C1strongest claim

We construct static, spherically symmetric black hole solutions in quasi-topological gravity (QTG) coupled to Born-Infeld nonlinear electrodynamics... for some of these models, charged black holes develop a curvature singularity at a finite radius in their interior. In contrast, in models such as a Born-Infeld-type QTG, charged black holes remain regular.

C2weakest assumption

The specific choices of QTG parameters that render vacuum black holes regular, together with the assumption that the spherically reduced action yields closed-form solutions without additional interaction terms between gravity and electrodynamics.

C3one line summary

Exact charged black hole solutions in quasi-topological gravity with Born-Infeld electrodynamics are constructed, revealing model-dependent interior regularity with some cases singular and others regular but with AdS cores.
