As. Majumdar et al., STABLE COMPACTIFICATION AND INFLATION FROM HIGHER-DIMENSIONAL BRANS-DICKE THEORY, Physics letters. Section B, 312(1-2), 1993, pp. 67-74
A higher-dimensional Brans-Dicke model of gravity is studied. It is sh
own that in the conformal Einstein frame, it is possible to obtain (a)
stable compactification of internal space, and (b) a viable scenario
for extended inflation.
