On the Trace-Free Einstein Equations as a Viable Alternative to General Relativity
George F. R. Ellis, Henk van Elst, Jeff Murugan +1
The quantum field theoretic prediction for the vacuum energy density leads to a value for the effective cosmological constant that is incorrect by between 60 to 120 orders of magni…
The Emergent Universe: An Explicit Construction
George F. R. Ellis, Jeff Murugan, Christos G. Tsagas
We provide a realisation of a singularity-free inflationary universe in the form of a simple cosmological model dominated at early times by a single minimally coupled scalar field…
Holonomy in the Schwarzschild-Droste Geometry
Tony Rothman, George F. R. Ellis, Jeff Murugan
Parallel transport of vectors in curved spacetimes generally results in a deficit angle between the directions of the initial and final vectors. We examine such holonomy in the Sch…
