| Outline of Final Research Achievements |
For the purpose of describing the nonlinear phenomena and observable features in the large-scale structure of the universe, the "integrated perturbation theory" is developed and completed. In the large-scale structure, there are complicated processes of dynamical nonlinear effects, nonlinear redshift-space distortions and galaxy biasing. This complicated problems are systematically treated by the theoretical method of the integrated perturbation theory. Various problems in the weakly nonlinear phenomena in the large-scale structure are actually shown to be solved by this general method. These findings are compared with large-scale numerical simulations, and the accuracy of the method and applicability region are quantified.
