SUR LES CHAMPS PHYSIQUES DE DIVERGENCE NULLE ET LES CHAMPS EN CORDE.
Résumé
We present a study of certain complex fields. The first study is made on the fields which preserve the shape volume along their continuous flow, i.e, the\ divergence of the fields is zero. The Lie derivative for these fields can be linked to an essentially self-adjoint operator. The spectral analysis and the extension of this operator in the Fock space $\mathcal{F}\left( L^{2}\left( \Omega,d\omega\right) \right)$ allows to quantify this field. The second study is made on fields said in strings. It is the geometrical representation which allows to quantify the product of the mass and the tension of the string.
