Abstract
A kinematical model (a parameterized deceleration parameter) and a dynamical model (a parameterized equation of state for dark energy) are constrained from the current observational data including the high-redshift Gamma-Ray Bursts (GRBs) data with a redshift range from 1.4 to 9. We obtain the stringent constraint on the values of current deceleration parameter q 0, current jerk parameter j 0, current equation of state for dark energy w 0de and transition redshift z T. In addition, we compare the difference of the constraint results between the kinematical and the dynamical scenarios.
