论文摘要
我们使用具有可变指数的广义非扩展tsallis熵来描述早期和晚期宇宙从热力学考虑因素的演变。我们分析中的一个新元素是在宇宙流体的描述中包含了大量粘度。使用广义的弗里德曼方程,获得了早期和晚期宇宙的描述。
We describe the evolution of the early and late universe from thermodynamic considerations, using the generalized non-extensive Tsallis entropy with a variable exponent. A new element in our analysis is the inclusion of a bulk viscosity in the description of the cosmic fluid. Using the generalized Friedmann equation, a description of the early and the late universe is obtained.
