Abstract

We show that, in a class of induced gravity models with (or without) torsion, the associated scalar field (the inflaton) has to be spatial independent in order to admit a Robertson-Walker type solution. Details of the proof are presented. The proof requires a great deal of mathematics which also serves as a pedagogical exercise by itself.
