Exploring the deviation of cosmological constant by a generalized pressure dark energy model
Jun-Chao Wang, Xin-He Meng
We bring forward a generalized pressure dark energy (GPDE) model to explore the evolution of the universe. This model has covered three common pressure parameterization types and c…

A pressure parametric dark energy model
Jun-Chao Wang, Xin-He Meng
In this paper, we propose a new pressure parametric model of the total cosmos energy components in a spatially flat Friedmann-Robertson-Walker (FRW) universe and then reconstruct t…
