Once we publish the Levi-Civita symbol like a determinant like we did above, the totally antisymmetric residence that it have results in being apparent: swapping any two indices corresponds to interchanging their corresponding rows during the matrix because of which the determinant, that is the Levi-Civita alone, alterations sign.
The Levi-Civita image is most frequently Employed in 3 and 4 dimensions, and also to some extent in two Proportions, so they're given here ahead of defining the overall case. Two dimensions[edit]

or Minkowski space. The values of the Levi-Civita symbol are impartial of any metric tensor and coordinate technique. Also, the precise term "symbol" emphasizes that it's not a tensor because of the way it transforms involving coordinate programs; nonetheless it could be interpreted like a tensor density.
