What happens to topological invariants (and black holes) in singularity-free theories?
Jens Boos
Potentials arising in ultraviolet-completed field theories can be devoid of singularities, and hence render spacetimes simply connected. This challenges the notion of topological i…

Non-singular "Gauss'' black hole from non-locality
Jens Boos
Cutting out an infinite tube around formally removes the Schwarzschild singularity, but without a physical mechanism this procedure seems ad hoc and artificial. In this paper…
