| ABSTRACT: |
Although the inflation in the early universe is strongly favored both theoretically and observationally, we are far from the complete understanding of it. Cosmological perturbation provides a powerful tool to extract informations of the early universe, which has been partially demonstrated by recent observations such as WMAP. In the seminar, I would like to briefly review the theory of cosmological perturbation and introduce my recent works, especially focusing on the topics of the non-Gaussianity of the primordial perturbation, which is now becoming an useful discriminator of the many existing inflation models.
