or Minkowski space. The values from the Levi-Civita image are unbiased of any metric tensor and coordinate process. Also, the particular phrase "symbol" emphasizes that it's not a tensor on account of how it transforms in between coordinate techniques; nonetheless it can be interpreted for a tensor density.
The term "n-dimensional Levi-Civita image" refers to The point that the number of indices to the image n matches the dimensionality in the vector House in concern, which can be Euclidean or non-Euclidean, for instance, R three displaystyle mathbb R ^ three
