Lorentzian orbifold



Riemannian geometry

Higher geometry



A Lorentzian orbifold is an orbifold with Lorentzian structure, hence like a Lorentzian manifold but possibly with singularities modeled on fixed points of local actions of finite groups by Lorentz transformations.


Discussion of Lorentzian orbifolds as target spacetimes in string theory:
