Abstract
The finite-dimensional Einstein-Maxwell-scalar field system, characterized by a spatially homogeneous or spatially self-similar gravitational field, is approached from a group-theoretical point of view. The field equations are expressed as a parametrized finite-dimensional mechanical system whose singularity behavior is readily apparent, using a method which allows one to consider all possible symmetry types simultaneously.
