Critical state of phantom universe
Yi-Huan Wei
The late-time evolution behavior of the autonomous system in the SO(1,1) dark energy model with power-law potential is studied. Big Rip may be a critical point of the autonomous sy…
Big Rip in SO(1,1) phantom universe
Yi-Huan Wei
For the inverse linear potential, the SO(1,1) field behaves as phantom for late time and the Big Rip will occur. The field approaches zero as time approaches the Big Rip, here. For…
Late-time phantom universe in dark energy model with exponential potential
Yi-Huan Wei
We discuss the late-time property of universe and phantom field in the SO(1,1) dark energy model for the potential with and two positive constants. We assu…
The power-law expansion universe and the late-time behavior
Yi-Huan Wei
Using the SNe Ia data we determine the three parameters in the power-law expanding universe model with time-dependent power \cite{W}. Inputting and , then we find the $\…
SO(1,1) dark energy model and the universe transition
Yi-Huan Wei, Yu Tian
We suggest a scalar model of dark energy with the SO(1,1) symmetry. The model may be reformulated in terms of a real scalar field and the scale factor so that the Lagrangia…
The power-law expansion universe and dark energy evolution
Yi-Huan Wei
In order to depict the transition from deceleration to acceleration expansion of the universe we use a power-law expansion scale factor, , with , and $…
