Click For Summary
The superpotential tensor in teleparallel gravity is associated with the conservation of the energy-momentum tensor, which arises from the Bianchi identities. Its divergence is zero, indicating that it yields a conserved current. This relationship highlights the connection between general covariance and energy conservation in the framework of gravity. For further insights, the book "Gravity and Strings" by Ortin provides additional commentary on this topic. Understanding the superpotential tensor is crucial for grasping the nuances of teleparallel gravity.

what is the meaning of superpotential tensor in teleparallel gravity ? it defined as :

Looking at

http://cds.cern.ch/record/478192/files/0011079.pdf

it seems that the divergence of this superpotential yields the conserved current due to the Bianchi identities. The divergence of this superpotential is then automatically zero.

You should check "Gravity and Strings" by Ortin, section 2.2 for some extra comments on this superpotential :)

So in the context of GR I would say that gct-invariance implies conservation of the energy momentum tensor, and this energy momentum tensor can be written as the divergence of the superpotential due to the Bianchi identities.
 
Thank u dude
 

Thread 'EPR revisited'

In an inertial frame of reference (IFR), there are two fixed points, A and B, which share an entangled state $$ \frac{1}{\sqrt{2}}(|0>_A|1>_B+|1>_A|0>_B) $$ At point A, a measurement is made. The state then collapses to $$ |a>_A|b>_B, \{a,b\}=\{0,1\} $$ We assume that A has the state ##|a>_A## and B has ##|b>_B## simultaneously, i.e., when their synchronized clocks both read time T However, in other inertial frames, due to the relativity of simultaneity, the moment when B has ##|b>_B##...
