The Jacobi identity holds for any group generator, so there may be other new discoveries around the corner. The group generator in the case of general relativity is the covariant derivative. In the Lorentz group of special relativity there are boost and rotation generators, and in the Poincare group there are boost, rotation and spacetime translation generators, introduced by Wigner. They key to progress is finding the equivalent of torsion in all these groups. There are also applications of the Jacobi identity in quantum mechanics, when it operates on the wavefunction. As is well known by now, torsion in ECE theory generates the field tensors in a space with non zero spin connection. I hope to have UFT313 finished and distributed tomorrow, once Horst has checked the final note 313(8). For example the First Evans identity is a cyclical relation between the field tensors either of gravitation or electromagnetism, or both. This may give a clue as to the interaction of electromagnetism and gravitation.
