| Outline of Final Research Achievements |
I have studied several extended gravity models and investigated if these models can be realistic. In parallel, I constructed models satisfying several constraints obtained from observations and theoretical consistencies, especially from the dark energy problem and the inflation in the early universe. I have also investigated the propagation of the gravitational waves in several models. In other works, I have investigated what kind of black hole solutions can
be possible in the framework of extended gravities and I have found new and exotic solutions. I also proposed models for solving the Hubble tension problem and investigated neutron stars' effect and tried to clarify how the effect can be approved.
