or Minkowski Room. The values from the Levi-Civita symbol are independent of any metric tensor and coordinate system. Also, the precise phrase "symbol" emphasizes that it's not a tensor on account of how it transforms amongst coordinate techniques; nonetheless it may be interpreted for a tensor density.

Certainly, there remain quite a few open up inquiries and areas of study associated with Levi-Civita properties in four dimensions.

wherever gab will be the representation of your metric in that coordinate technique. We can easily likewise consider a contravariant Levi-Civita tensor by raising the indices Together with the metric as standard,
The expression "n-dimensional Levi-Civita symbol" refers to The reality that the amount of indices within the symbol n matches the dimensionality of your vector space in dilemma, which can be Euclidean or non-Euclidean, by way of example, R 3 displaystyle mathbb R ^ 3

On the pseudo-Riemannian manifold, 1 may determine a coordinate-invariant covariant tensor discipline whose coordinate representation agrees With all the Levi-Civita image wherever the coordinate process is these kinds of that the basis with the tangent Room is orthonormal with respect towards the metric and matches a particular orientation.
