Résumé
We write the identities relative to a density which depends of tensors, of the first and second derivatives of these tensors, of a connection and of the first derivatives of this connection. By means of these identities, we build up skew symmetric pseudo-tensors (complexes) and conservative pseudo tensors, wich generalize those introduced by Møller in general relativity. The variances of the functions in them are indicated. Finally, we apply the obtained results to some particular cases.
