| Research Abstract |
We have explored modified theories of gravity as an alternative to dark energy that would be the origin of the current cosmic acceleration. We have studied observational and experimental consequences of modified gravity, and considered how one can distinguish different theories of gravitation. We have also proposed the most general model of inflation in the early Universe, based upon some generic class of modified gravity theories.
