| Outline of Final Research Achievements |
Basic research for simulation of non-spherical primordial black hole formation has been performed, and the development led to the success in the simulation starting from a non-spherical realistic initial data for primordial black hole formation in the beginning of 2020 fiscal year.
The procedure of calculating primordial black hole abundance has been improved much, and it contributed to the progress in estimation of primordial black hole abundance.
