Teleparallel Theory of Gravity by Hayashi-Shirafuji.
Abstract:
The generally accepted theory of gravity is Einstein's General Theory of Relativity (GTR),
where gravity is a consequence of the curvature of space-time due to the presence of matter.
Despite the great success of this approach, there are certain difficulties with quantizing GTR
and with describing Dark Matter within its framework. There is an idea to modify the theory of gravity in such a way
that the effects of Dark Matter can be described as purely gravitational.
One of the variants of such a modification is the teleparallel theory by Hayashi-Shirafuji,
where the main geometric characteristic is torsion, and the dynamic variable is a tetrad.
