The Levi-Civita symbol is most frequently Employed in 3 and four dimensions, and to some extent in two Proportions, so these are presented here before defining the general circumstance. Two dimensions[edit]

or Minkowski Area. The values of the Levi-Civita image are impartial of any metric tensor and coordinate technique. Also, the particular phrase "image" emphasizes that it's not a tensor as a result of how it transforms in between coordinate systems; however it might be interpreted as being a tensor density.
These properties are important for comprehension the conduct in the tensor in various coordinate systems.

Certainly, there are still many open thoughts and areas of exploration associated with Levi-Civita Houses in 4 dimensions.
This tensor should not be confused With all the tensor density industry described over. The presentation in this portion intently follows Carroll 2004.

The subsequent are samples of the general identification above specialised to Minkowski House (with the detrimental indicator arising within the odd range of negatives while in the signature of the metric tensor in possibly indication convention):

For each and every sequence of nonempty open sets There's a disjoint sequence of nonempty open up sets "under" it
The covariant Levi-Civita tensor (often known as the Riemannian quantity form) in any coordinate procedure that matches the chosen orientation is
where gab would be the illustration of your metric in that coordinate system. We are able to similarly contemplate a contravariant Levi-Civita tensor by raising the indices Together with the metric as regular,
