Hi there,
I am trying to do some Levi-Civita contractions in D = 3 but it doesn’t seem to work. For example, I can do
LC[a,b,c,d]LC[a,b,c,e]//Contract
in D=4 and get the contraction (the metric), but doing
LC[a,b,c]LC[a,b,e]//Contract
in D = 3 does not give me the equivalent. I have tried using SetOptions[LeviCivita, Dimension -> 3] and replacing LC with LCD, but ultimately it only seems to work with four index tensors.
Any ideas how I can implement this for three-index LC’s?
Thanks.
