Geometric \(\sigma\)-models

1998
Summary: A class of nonlinear \(\sigma\)-models coupled to gravity is defined by identifying the coordinates of spacetime with the components of a set of scalar fields. The obtained theories have purely geometric character and necessarily possess soliton solutions with topologically nontrivial scalar sectors.
