or Minkowski Room. The values in the Levi-Civita symbol are unbiased of any metric tensor and coordinate process. Also, the precise time period "symbol" emphasizes that it is not a tensor due to how it transforms among coordinate programs; having said that it can be interpreted for a tensor density.
The expression "n-dimensional Levi-Civita image" refers to The truth that the quantity of indices to the image n matches the dimensionality from the vector House in question, which can be Euclidean or non-Euclidean, such as, R three displaystyle mathbb R ^ 3
From this behavior, we can certainly deduce what $epsilon^ ij4k $ could be without the need of dealing with the computations Once more: it is simply the result of exchanging the last two indices of $epsilon^ ijk4 $,
