Indeed, there remain several open up questions and parts of research connected with Levi-Civita properties in 4 dimensions.
This tensor really should not be puzzled While using the tensor density area pointed out earlier mentioned. The presentation Within this segment carefully follows Carroll 2004.
The Levi-Civita image enables the determinant of a sq. matrix, as well as cross merchandise of two vectors in 3-dimensional Euclidean House, to become expressed in Einstein index notation.

With a pseudo-Riemannian manifold, one particular might outline a coordinate-invariant covariant tensor field whose coordinate representation agrees While using the Levi-Civita symbol anywhere the coordinate procedure is this sort of that The premise from the tangent Place is orthonormal with regard towards the metric and matches learn more a particular orientation.
where gab may be the representation on the metric in that coordinate process. We can similarly contemplate a contravariant Levi-Civita tensor by elevating the indices Together with the metric as regular,
