or Minkowski Room. The values from the Levi-Civita symbol are unbiased of any metric tensor and coordinate process. Also, the particular term "image" emphasizes that it is not a tensor because of the way it transforms among coordinate systems; having said that it could be interpreted as being a tensor density.

The Levi-Civita symbol allows the determinant of the square matrix, and also the cross item of two vectors in a few-dimensional Euclidean Place, to get expressed in Einstein index notation.

The Levi-Civita symbol is most often used in three and four dimensions, and to some extent in two Proportions, so these are offered right here just before defining the general scenario.

The subsequent are examples of the final identification above specialised to Minkowski Room (with the detrimental signal arising within the odd range of negatives while in the signature from the metric tensor in possibly signal Conference):
