Constructor Detail

LeviCivitaSimplifyTransformation

public LeviCivitaSimplifyTransformation(SimpleTensor leviCivita,
                                        boolean minkowskiSpace)

Creates transformation, which simplifies combinations of Levi-Civita tensors in Euclidean or Minkowski space.

Parameters:

leviCivita - tensor, which will be considered as Levi-Civita tensor

minkowskiSpace - if true, then Levi-Civita tensor will be considered in Minkowski space (so e.g. e_abcd*e^abcd = -24), otherwise in Euclidean space (so e.g. e_abcd*e^abcd = +24)
