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). LeviCivita[][ .] evaluates to Eps[LorentzIndex[], LorentzIndex[], ..., Momentum[], ...].
