Subject: Background to Paper 105
Date: Wed, 30 Apr 2008 09:47:13 EDT
The background to paper 105, in which the metric element is derived from the Bianchi identity, is the use of a symmetric metric, but without assuming that the connection is torsion free. The metric compatibility connection is used implicitly because if a connection is metric compatible the metric is always parallel transported. Then the invariant in paper 105 is constructed but without assuming a torsion free connection. So this completes a series of technical notes to the general readership explaining the background to papers 93 to 110. The basic dynamical equation is no longer EH but the four vectro equations derived from the Bianchi identity and its Hodge dual.
