Coframe geometry and gravity
The possible extensions of GR for description of fermions on a curved space, for supergravity and for loop quantum gravity require a richer set of 16 independent variables. These variables can be assembled in a coframe field, i.e., a local set of four linearly independent 1-forms. In this chapter we study the gravity field models based on a coframe variable alone. We give a short review of the ...
متن کاملGravitomagnetism in Teleparallel Gravity
Abstract The assumption that matter charges and currents could generate fields, which are called, by analogy with electromagnetism, gravitoeletric and gravitomagnetic fields, dates from the origins of General Relativity (GR). On the other hand, the Teleparallel Equivalent of GR (TEGR), as a gauge theory, seems to be the ideal scenario to define these fields, based on the gauge field strength co...
متن کاملCoframe geometry, gravity and electromagnetism
The extensions of GR for description of fermions on a curved space, for supergravity, and for the loop quantum gravity ordinary use a set of 16 independent variables instead of 10 components of metric. These variables can be assembled in a coframe field, i.e., a set of four linearly independent 1-forms. In this presentation we review a geometrical structure based on the coframe field. We constr...
متن کاملTesting Weak-Field Gravity
One of the most important problems in science today is the origin of \dark matter". Much of our understanding of the history and present state of the universe depends upon conjectures about the nature of dark matter. In some sense, our knowledge rests upon a \house of cards" which won't be buttressed until progress is made in identifying what dark matter represents. Most research today is found...
متن کاملThe Symmetric Teleparallel Gravity
We study symmetric teleparallel (STP) gravity model, in which only spacetime nonmetricity is nonzero. First we obtain STP equivalent Einstein-Hilbert Lagrangian and give an approach for a generic solution in terms of only metric tensor. Then we obtain a spherically symmetric static solution to the Einstein’s equation in STP space-time and discuss the singularities. Finally, we study a model giv...
