Oscillating cosmic evolution and constraints on big bang nucleosynthesis in the extended Starobinsky model
Jubin Park, Chae-min Yun, Myung-Ki Cheoun +1
We investigate the cosmic evolutions in the extended Starobinsky model (eSM) obtained by adding one term to the Starobinsky model. We discuss the possibility of vari…

An exact solution of the higher-order gravity in standard radiation-dominated era
Chae-min Yun, Jubin Park, Myung-Ki Cheoun +1
We report that the standard evolution of radiation-dominated era (RDE) universe is a sufficient condition for solving a sixth order gravitational field equation…

Gravitational wave from cosmic inflation in a gravity with two small four-derivative corrections
Chae-min Yun
We investigate a model of inflationary cosmology where the minimally coupled scalar field theory is modified by additional correction terms. Among the most general ten correction t…
