Regular BTZ black holes from an infinite tower of corrections (2504.08565v1)
Published 11 Apr 2025 in gr-qc and hep-th
Abstract: We explore $2+1$-dimensional scalar-tensor theories derived from well-defined dimensional regularizations of the Lovelock invariants. In the limit where an infinite series of corrections is included, we obtain theories that admit fully regular black hole solutions. We analyze the properties of these regular black holes, investigate geodesics in these spacetimes, and examine the tidal forces, finding they remain finite everywhere.
