Area metric gravity and accelerating cosmology
Raffaele Punzi, Frederic P. Schuller, Mattias N. R. Wohlfarth
Area metric manifolds emerge as effective classical backgrounds in quantum string theory and quantum gauge theory, and present a true generalization of metric geometry. Here, we co…
Geometry for the accelerating universe
Raffaele Punzi, Frederic P. Schuller, Mattias N. R. Wohlfarth
The Lorentzian spacetime metric is replaced by an area metric which naturally emerges as a generalized geometry in quantum string and gauge theory. Employing the area metric curvat…
Geometric obstruction of black holes
Raffaele Punzi, Frederic P. Schuller, Mattias N. R. Wohlfarth
We study the global structure of Lorentzian manifolds with partial sectional curvature bounds. In particular, we prove completeness theorems for homogeneous and isotropic cosmologi…
