Remarks on some vacuum solutions of scalar-tensor cosmological models
We present a class of exact vacuum solutions corresponding to de Sitter and warm inflation models in theframework of scalar-tensor cosmologies. We show that in both cases the field equations reduce to planar dynamicalsystems with constraints. Then, we carry out a qualitative analysis of the models b...
