THE STABILITY OF A KIND OF COSMOLOGICAL MODEL
View through CrossRef
The stability of a kind of cosmological models is given. The variations of the cosmological model for parameters λ and k were discussed respectively. Near λ=0, the cosmological model is unstable with the change of λ, and near λ=β=0, the cosmological model is unstable with the change of k. So when we consider the stable cosmological model, we must consider the no-zero cosmological constant.

Title: THE STABILITY OF A KIND OF COSMOLOGICAL MODEL
Description:
The stability of a kind of cosmological models is given.
The variations of the cosmological model for parameters λ and k were discussed respectively.
Near λ=0, the cosmological model is unstable with the change of λ, and near λ=β=0, the cosmological model is unstable with the change of k.
So when we consider the stable cosmological model, we must consider the no-zero cosmological constant.
