Levi-Civita Rhymes with Lolita William O. Straub Pasadena, California 91104 February 2, 2017 exchange antisymmetry of the symbols neatly parallels the symmetry of the ordinary two-index Kronecker symbol . Indeed, we will see that any LC symbol consists entirely of a string of Kronecker symbols.

Four dimensions In four dimensions, the Levi-Civita symbol is defined by: These values can be arranged into a 4 × 4 × 4 × 4 array, although in 4 dimensions and higher this is difficult to draw.

In mathematics, particularly in linear algebra, tensor analysis, and differential geometry, the Levi-Civita symbol represents a collection of numbers; defined from the sign of a permutation of the natural numbers 1, 2, …, n, for some positive integer n. It is named after the Italian mathematician and physicist Tullio Levi-Civita.

In Four-dimensional space, the Levi-Civita symbol is defined as: ε i j k l =. { + 1 if ( i, j, k, l) is an even permutation of ( 1, 2, 3, 4) − 1 if ( i, j, k, l) is an odd permutation of ( 1, 2, 3, 4) 0 otherwise. Let's suppose that I fix the last index ( l=4 for example). I guess that the 4-indices symbol can now be replaced with a 3-indices …
