In the theory of Riemannian and pseudo-Riemannian manifolds the term covariant derivative is often used for the Levi-Civita connection. The components of this connection with respect to a It returns 0 in all cases where there is a repeated index. In general, the levi-civita symbol can be defined for any number of dimensions (number of indices given), and returns values for incomplete lists of indices (such as [3,4,5]) as if the elements not given in that list were prepended in ascending order e_3,4,5 = e_1,2,3,4,5 = 1. Here it is: Se hela listan på tau.ac.il LeviCivita Description LeviCivita[] is an input function for the totally antisymmetric Levi-Civita tensor.It evaluates automatically to the internal representation Eps[ LorentzIndex[], LorentzIndex[], LorentzIndex[], LorentzIndex[] ] (or with a second argument in LorentzIndex for the Dimension, if the option Dimension of LeviCivita is changed).
