| Outline of Final Research Achievements |
In our universe physical phenomena at various scales occur constantly, having mutual influence on each other. I consider it necessary for physics at the largest scales, i.e. cosmology, to be connected with physics at the shortest scales, i.e. quantum gravity. I thus continued my research to deepen our understanding of the universe based on quantum gravity and published 47 research papers in referred journals in 5 years. Concretely, I worked on (i) cosmology based on quantum gravity, (ii) cosmology based on Lorentz-violating gravity theory, (iii) cosmology based on nonlinear massive gravity, and (iv) other related subjects.
