We describe the evolution of the early and late universe from thermodynamic considerations, using the generalized nonextensive 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.

具有粘度的熵宇宙学的热力学方面

我们从热力学考虑描述了早期和晚期宇宙的演化,使用具有可变指数的广义非广延 Tsallis 熵。我们分析中的一个新元素是在宇宙流体的描述中包含体积粘度。使用广义弗里德曼方程,获得了早期和晚期宇宙的描述。
