When we write the Levi-Civita image being a determinant like we did earlier mentioned, the absolutely antisymmetric home that it possess will become apparent: swapping any two indices corresponds to interchanging their corresponding rows while in the matrix as a result of which the determinant, that's the Levi-Civita itself, changes signal.

Levi-Civita properties in four Proportions confer with a set of mathematical Qualities that describe the behavior of the mathematical object named go here a 4-dimensional Levi-Civita tensor. This tensor is used in differential geometry to determine the curvature of the 4-dimensional Area.
but recognize that In case the metric signature incorporates an odd number of negative eigenvalues q, then the sign from the components of the tensor differ from the standard Levi-Civita image:
