| Research Abstract |
To understand the large-scale structure of the universe, and to constrain cosmological models from large-scale observations, it is necessary to elucidate effects of nonlinearity in observable quantities of density fluctuations in the universe. The cosmological perturbation theory is largely extended and generalized to include nonlinearities in observable quantities together with the nonlinearities in dynamics, and fundamental methods are developed in this field of research.
