Abstract: (arXiv)
In this work, we analyze the coset space dimensional reduction scheme to construct pure Yang--Mills fields on maximally symmetric spacetimes given as cylinders over cosets. Particular cases of foliations using HnH^n, dSn_n and AdSn_n slices as non-compact symmetric spaces are solved, compared to previous results in the literature, and generalized in a structured fashion. Coupling to General Relativity in FLRW-type universes is introduced via the cosmological scale factor. For the hyperbolic slicing, the dynamics of the Einstein--Yang--Mills system is analytically solved and discussed. Finally, we generalize the analysis to warped foliations of the cylinders, which enlarge the range of possible spacetimes while also introducing a Hubble friction-like term in the equation of motion for the Yang--Mills field.
