| Outline of Final Research Achievements |
The invariance under spacial scale transformation plays an important role in the conservation of curvature perturbation on super horizon scales.The effective action that received the loop correction is also proved to maintain this invariance. Besides the conservation of curvature perturbation, there are also universal properties such as consistency relations. Although these are often claimed to be related to the large gauge transformation, we show that locality conditions are further needed. It was also shown that the conditions for the observable physical quantities not to have infrared divergences are the same locality conditions. On the other hand, in collaboration with a graduate student, Mr. Junsei Tokuda, we formulated a systematic method to derive an effective equation of motion for long wavelength modes of a scalar field on a De Sitter background spacetime, and we showed that the dynamics governed by this equation can be interpreted as a classical stochastic process.
