| Summary: | 碩士 === 國立交通大學 === 物理研究所 === 95 === The inflation theory is known to solve the horizon and flatness problems. However, to restrict the initial universe to be isotropic as described by FRW metric is not natural. Hence, we release the constraint of isotropy but still require the universe to be homogeneous, i.e. we take Bianchi spaces into induced gravity inflation. We re-examine a problem about action principle which may be easily ignored in the end. After some detailed study, we find that it is correct to do variation of the action with respect to scale factors for Bianchi IX model up to some higher derivative Lagrangian corrections.
