The vielbein of FlatMetric returns the signature itself and an identity vielbein (up to ordering and signs):
In[1]:=
 | MetricVielbein |
 | FlatMetric |
Out[1]=
{{{-1,0,0,0},{0,-1,0,0},{0,0,-1,0},{0,0,0,1}},{{0,0,0,1},{0,0,1,0},{0,1,0,0},{1,0,0,0}}}
Round-trip: reconstructing from the vielbein returns the original metric (House rule #3):
η
In[2]:=
Moduleη=
[1,3],sig,e,{sig,e}=
[η];Transpose[e].sig.e===η
 | FlatMetric |
