The Levi-Civita symbol is most frequently Utilized in three and 4 dimensions, and also to some extent in two Proportions, so they're offered listed here in advance of defining the general scenario. Two Proportions[edit]
= δ i l ( δ j m δ k n − δ j n δ k m ) − δ i m ( δ j l δ k n − δ j n δ k l ) + δ i n ( δ j l δ k m − δ j m δ k l ) .
ε i j ε i n = δ j n displaystyle varepsilon _ ij varepsilon ^ in = delta _ j ^ n
Levi-Civita properties in 4 Proportions are closely relevant to Einstein's theory of normal relativity, which describes the curvature of spacetime inside the existence of massive objects.

With a pseudo-Riemannian manifold, a single may perhaps define a coordinate-invariant covariant tensor discipline whose coordinate illustration agrees with the Levi-Civita image wherever the coordinate technique is these types of that the basis in the tangent Place is orthonormal with regard towards the metric and matches a specific orientation.
