The Levi-Civita symbol is most often Employed in three and 4 Proportions, and also to some extent in two dimensions, so these are given below just before defining the final situation. Two Proportions[edit]

The phrase "n-dimensional Levi-Civita symbol" refers to The point that the amount of indices to the image n matches the dimensionality from the vector Room in dilemma, which may be Euclidean or non-Euclidean, by way of example, R three displaystyle mathbb R ^ three
From this habits, we can easily deduce what $epsilon^ ij4k $ could well be devoid of dealing with the computations Again: it is simply the results of exchanging the last two indices of $epsilon^ ijk4 $,

This tensor really should not be puzzled While using the tensor density area outlined previously mentioned. The presentation Within this part intently follows Carroll 2004.
The Levi-Civita symbol makes it possible for the determinant of the square matrix, as well as the cross product or service of two vectors in three-dimensional Euclidean Room, to generally be expressed in Einstein index notation.
Levi-Civita Houses in 4 dimensions make reference to a set of mathematical Attributes that explain the habits of the mathematical object named a four-dimensional Levi-Civita tensor. This tensor is Utilized in differential geometry to define the curvature of the four-dimensional Room.
