Abstract: | Extended inflation solution in Brans-Dicke theory given by Mathiazhagan and Johri (MJ) is shown as the unique solution only
if the scale factor is assumed to be a power function of the scalar field. Only the consistent solution amongst the set of
solutions given by Patra, Roy and Ray is found identical to the MJ solution. Both exponential inflation and power function
inflation are studied in general scalar tensor theory where the parameter to is a function of the scalar, field. It is noted
that exponential inflation is forbidden in Brans-Dicke theory wherew is a constant. |
