Gravity a la Born-Infeld
Mattias N. R. Wohlfarth
A simple technique for the construction of gravity theories in Born-Infeld style is presented, and the properties of some of these novel theories are investigated. They regularize…
Inflationary Cosmologies from Compactification?
Mattias N. R. Wohlfarth
We consider the compactification of (d+n)-dimensional pure gravity and of superstring/M-theory on an n-dimensional internal space to a d-dimensional FLRW cosmology, with spatial cu…
Accelerating Cosmologies and a Phase Transition in M-Theory
Mattias N. R. Wohlfarth
M-theory compactifies on a seven-dimensional time-dependent hyperbolic or flat space to a four-dimensional FLRW cosmology undergoing a period of accelerated expansion in Einstein c…
Accelerating Cosmologies from Compactification
Paul K. Townsend, Mattias N. R. Wohlfarth
A solution of the (4+n)-dimensional vacuum Einstein equations is found for which spacetime is compactified on a compact hyperbolic manifold of time-varying volume to a flat four-di…
