In fact if we have the metric Nab+Hab..where Nab is the MInkowskian metric and Hab a small perturbation of it [Hab]<<1. then :
a)We know that if Hab were 0 then we know the group and the invariants..but could we construct the invariants (and the K-g and Dirac equations) when the metric is Nab+Hab?....
b)What would be the group of this new metric?..
