The results presented in this report are mainly based on our work recently published /D.V.Duc, P.C.Hoa, J.Mod.Phys., vol.5, p.2106(2014)/. The concept of generally covariant duality is treated within the framework of vierbein formalism. The equations for associated scalar fields are derived from vierbein postulate. The existence of scalar tachyons is predicted with the masses completely determined by Einstein cosmological constant.
