Examples of Levi-Civita properties in four dimensions involve the symmetric and antisymmetric character of the tensor, its relation to your metric tensor, and its transformation Homes under coordinate transformations.

then remaining aspect is zero, and ideal aspect is usually zero considering that two of its rows are equivalent. Equally for j c = j c + one displaystyle j_ c =j_ c+one

This tensor really should not be perplexed While using the tensor density area talked about higher than. The presentation With this section intently follows Carroll 2004.

The Levi-Civita image makes it possible for the determinant of the sq. matrix, and also the cross products of two vectors in three-dimensional Euclidean space, to generally be expressed in Einstein index notation.

Using the capital pi notation Π for normal multiplication of numbers, an explicit expression for the image is:[citation required]

but observe that If your metric signature incorporates an odd range of negative eigenvalues q, then the indication of your factors of the tensor differ from your normal Levi-Civita symbol:
