Following a recent approach, complete and analytic solutions (brane and bulk) of regular black holes are shown in a brane context. The metrics are regular both on the four-dimensional brane and in the five-dimensional bulk. Like many brane world scenarios, the bulk spacetime is asymptotically anti-de Sitter. On the other hand, a de Sitter core on the brane avoids the singularity inside the event horizon, providing then well-known regular black holes on the brane. From the bulk perspective, the regular black holes are five-dimensional objects, with the event horizon extending to the extra dimension, but the de Sitter core is entirely on the four-dimensional brane.

Geodesic dynamics in brane-de Sitter wormholes
For an asymptotically de Sitter brane wormhole, the throat is shown to be an unstable fixed point and photon sphere, with a claimed Bogdanov-Takens bifurcation for radial null geodesics.

Embedding Wormholes and Dyonic Black Strings in Warped Braneworlds via Local Sum Rules
Embedding of Ellis-Bronnikov wormhole and NED-sourced magnetic/dyonic black strings into RS braneworlds using Local Sum Rules; the dyonic q→0 limit is inconsistent as written.

Wormholes from beyond
Using the Nakas-Kanti top-down approach, the author embeds the Morris-Thorne and Molina-Neves wormholes in a regular five-dimensional anti-de Sitter bulk, so the wormhole on the brane is supported entirely by bulk fields.
