Gauge-Invariant Gravitational Wave Polarization in Metric f(R) Gravity with Cosmological Implications
Ramesh Radhakrishnan, David McNutt, Delaram Mirfendereski +4
We develop a fully gauge invariant analysis of gravitational wave polarizations in metric f(R) gravity with a particular focus on the modified Starobinsky model, whose constant cur…

Killing Invariants: An approach to the sub-classification of geometries with symmetry
C. Brown, M. Gorban, W. Julius +3
In principle, the local classification of spacetimes is always possible using the Cartan-Karlhede algorithm. However, in practice, the process of determining equivalence of two spa…
