| Outline of Final Research Achievements |
Dark matter played a central role in shaping the structure of the universe, but its identity is shrouded in mystery. In this study, we present the possibility of primordial black holes as a part of dark matter and their formation process, the elaboration of cosmological restrictions on the pair annihilation and decay of dark matter, the new formation process of axions and light dark photon dark matter, a detailed comparison between the Lagrangian perturbation theory and Vlasov-Poisson simulations of the phenomenon called shell crossing during halo formation, the construction of a unified model of inflation and dark matter, and the derivation of restrictions on the isocurvature fluctuations of dark matter and dark energy based on the Swampland conjecture.
