On intrinsic symmetry in Gurzadyan-Xue cosmological models
H. Khachatryan, G. V. Vereshchagin, G. Yegorian
Abstract
Analysis of cosmological solutions of GX dark energy models shows the presence of a separatrix in the phase space of solutions which divides them into two classes: Friedmannian-like with initial singularity and non-Friedmannian solutions. The invariants are found, that reveal the intrinsic symmetry in GX models.
