The Relativistic Gravitational Field of a Spherically Symmetric Extended Body
Y. Friedman, S. I. Klimovsky
We investigate the gravitational field of an extended spherically symmetric body within the framework of Extended Relativity (ER), a Lorentz-covariant formulation of relativistic g…
Polarization structure of gravitational waves in extended relativity
Yaakov Friedman
We analyze the polarization structure of gravitational waves in the framework of Extended Relativity (ER), using the deviation tensor as the fundamental observable quantity. Starti…
Two-timescale evolution of extreme-mass-ratio inspirals: waveform generation scheme for quasicircular orbits in Schwarzschild spacetime
Jeremy Miller, Adam Pound
Extreme-mass-ratio inspirals, in which a stellar-mass compact object spirals into a supermassive black hole in a galactic core, are expected to be key sources for LISA. Modelling t…
Premetric teleparallel theory of gravity and its local and linear constitutive law
Yakov Itin, Yuri N. Obukhov, Jens Boos +1
We continue to investigate the premetric teleparallel theory of gravity (TG) with the coframe (tetrad) as gravitational potential. We start from the field equations and a local and…
Premetric equivalent of general relativity: Teleparallelism
Yakov Itin, Friedrich W. Hehl, Yuri N. Obukhov
In general relativity (GR), the metric tensor of spacetime is essential since it represents the gravitational potential. In other gauge theories (such as electromagnetism), the so-…
On Kottler's path: origin and evolution of the premetric program in gravity and in electrodynamics
Friedrich W. Hehl, Yakov Itin, Yuri N. Obukhov
In 1922, Kottler put forward the program to remove the gravitational potential, the metric of spacetime, from the fundamental equations in physics as far as possible. He successful…
