Abstract
Quantum dynamics of the Brans-Dicke field has been studied in hyperext ended inflationary models. A general expression for the density pertur bations arising out of such quantum fluctuations has been derived and used to evaluate the density perturbations for the special case of con stant omega (extended inflation) and shown to be consistent with the s tandard analysis. A simple model of hyperextended inflation is also co nsidered.
