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…
Cosmology as Geodesic Motion
Paul K. Townsend, Mattias N. R. Wohlfarth
For gravity coupled to N scalar fields with arbitrary potential V, it is shown that all flat (homogeneous and isotropic) cosmologies correspond to geodesics in an (N+1)-dimensional…
Sectional Curvature Bounds in Gravity: Regularisation of the Schwarzschild Singularity
Frederic P. Schuller, Mattias N. R. Wohlfarth
A general geometrical scheme is presented for the construction of novel classical gravity theories whose solutions obey two-sided bounds on the sectional curvatures along certain s…
