Spherically-symmetric non-linear sigma model: the exact solutions obtained with isometrical embedding method
The method to generate exact cosmological solutions in the frame of the spherically-symmetric non-linear sigma model offered in the present paper. This method is based on the isometrical embeddings of the target space (non-linear sigma-model fields chiral space) into space-time. Also the method appl...
