When we write the Levi-Civita image to be a determinant like we did previously mentioned, the totally antisymmetric residence that it have gets to be obvious: swapping any two indices corresponds to interchanging their corresponding rows in the matrix on account of which the determinant, that is the Levi-Civita by itself, variations indicator.

On the pseudo-Riemannian manifold, 1 may define a coordinate-invariant covariant tensor industry whose coordinate illustration agrees While using the Levi-Civita symbol where ever the coordinate process is this sort of that The idea on the tangent space is orthonormal with respect into the metric and matches a selected orientation.
The real key defining house in the image is whole antisymmetry in the indices. When any two indices are interchanged, equal or not, the image is negated:
