@article{Majumdar1997ConstraintsOH, title={Constraints on higher dimensional models for viable extended inflation}, author={Archan S. Majumdar}, journal={Physical Review D}, year={1997}, volume={55}, pages={6092-6098} }

We consider two kinds of higher dimensional models which upon dimensional reduction lead to Jordan-Brans-Dicke-type effective actions in four dimensions with the scale factor of the extra dimensions playing the role of the JBD field. These models are characterized by the potential for the JBD field which arises from the process of dimensional reduction, and by the coupling of the inflaton sector with the JBD field in the Jordan frame. Taking into account the fact that these models allow the…
