论文摘要
为了研究动态系统中的重力与热力学之间的关系，我们将弗里德曼 - 莱玛·罗伯特森 - 罗伯逊 - 沃克（FLRW）时空的明显视野解释为热力学系统。我们在熵表示中得出相应的基本方程，并探讨要求履行热力学经典定律的后果。我们详细调查了有或没有宇宙常数的FLRW时空的情况。我们表明，只有在某些条件下才有可能将明显的视野解释为热力学系统，因为类比并不总是有效，对于进入地平线动力学的参数的所有值，当然也不适合其整个演变。
To investigate the relationship between gravity and thermodynamics in the case of dynamic systems, we interpret the apparent horizon of the Friedmann-Lemaître-Robertson-Walker (FLRW) spacetime as a thermodynamic system. We derive the corresponding fundamental equation in the entropy representation and explore the consequences of demanding the fulfillment of the classical laws of thermodynamics. We investigate in detail the case of an FLRW spacetime with and without cosmological constant. We show that the interpretation of the apparent horizon as a thermodynamic system is possible only under certain conditions because the analogy is not always valid for all the values of the parameters entering the dynamics of the horizon and certainly not for its entire evolution.
