Matrix valued differential forms #159

Open kpeeters opened 4 years ago

kpeeters commented 4 years ago

The can_swap functions silently ignore that differential forms may be matrix-valued and hence not pick up the 'standard' sign; see

https://cadabra.science/qa/1276/manipulating-matrix-valued-differential-forms

for an example. Need at least SelfAntiCommuting and SelfNonCommuting tested whenever differential forms are involved.
