摘要

考虑了充满一般萨里斯全息暗能量的非平坦宇宙的宇宙学演化。我们假设全息分量的密度定义为~ L2γ−4，其中γ是不可加性参数，L是视界的长度。研究了暗物质与全息暗能量之间可能相互作用的影响。我们还考虑了宇宙从早期物质主导时代的渐近演化，并建立了γ<；1的de Sitter吸引子的存在性。

Non-flat universe with Tsallis holographic dark energy

The cosmological evolution of non-flat universe filled with general Tsallis holographic dark energy is considered. We assumed that the density of the holographic component is defined as

\sim L^{2 γ - 4}

where

γ

is the nonadditivity parameter and

L

is the length of the event horizon. The influence of possible interaction between dark matter and holographic dark energy is investigated. We also considered asymptotic evolution of universe from an early matter dominated epoch and established the existence of de Sitter attractor for

γ < 1
