鬼场暗能量密度的宇宙演化
Cosmological evolution of the ghost dark energy density
摘要
Abstract
A ghost dark energy was recently proposed to explain the present acceleration of the universe expansion . Based on the relation between ghost dark energy and Hubbard function the Friedman equation was solved and the cosmological evolution of the ghost dark energy density and its equation of state were obtained .It was found that the dimensionless energy density of ghost tends to 1 and the parameter of equation of state tends to -1 in the late time presenting the form of cosmological constant .关键词
