Homogeneous and isotropic closed cosmologies with a gauge sector
The authors study in a systematic way the kinematics and dynamics of closed Friedmann-
Robertson-Walker cosmologies in the presence of a gauge sector, with an arbitrary gauge
group. For this purpose they complement the SO (4)-invariant ansatz for the metric with SO
(4)-symmetric ansatze for the matter fields. The dynamics of the resulting Lagrangian system
with a finite number of degrees of freedom is studied for the case of Einstein-Yang-Mills-
Higgs theories with an SO (N) gauge group.

Abstract
The authors study in a systematic way the kinematics and dynamics of closed Friedmann-Robertson-Walker cosmologies in the presence of a gauge sector, with an arbitrary gauge group. For this purpose they complement the SO (4)-invariant ansatz for the metric with SO (4)-symmetric ansatze for the matter fields. The dynamics of the resulting Lagrangian system with a finite number of degrees of freedom is studied for the case of Einstein-Yang-Mills-Higgs theories with an SO (N) gauge group.
