“…In the present paper we continue an investigation of the model of an extended manifold introduced in [1][2][3]. There we discussed a model of manifold which consists two, at least, parts related by the classical symmetry which reverse charge, parity, time and mass (CPTM symmetry) preserving a form of the metric g at the case of the zero cosmological constant: q → − q , r → −r , t → − t , m grav → − mgrav ; q , r , t , mgrav > 0 ;…”
