| Research Abstract |
We study the so called "dark energy problem", which is one of the most important subjects of modern cosmology, from three approaches : (1) exotic fluid of dark energy (2) modified gravity theories (3) the possibility of other natural models. We have pointed out that it is important to analyze a strong gravitational system such as a black hole or a neutron star which is coupled to dark energy.
