On the exact entropy of black holes
João Gomes, Huibert het Lam, Grégoire Mathys
We study the exact entropy of four-dimensional black holes in M-theory both from the brane and supergravity points of view. On the microscopic side the degeneracy i…

Four-dimensional black hole entropy from F-theory
Thomas W. Grimm, Huibert het Lam, Kilian Mayer +1
We study the central charges and levels of a two-dimensional superconformal field theory describing four-dimensional BPS black holes in F-theory. These arise from D3-bran…

Singularities in FLRW Spacetimes
Huibert het Lam, Tomislav Prokopec
We point out that past-incompleteness of geodesics in FLRW spacetimes does not necessarily imply that these spacetimes start from a singularity. Namely, if a test particle that fol…
