论文摘要
Renyi的熵概述了一组数据估计，该数据估计总结了众所周知的香农熵，并获得了相当大的特性。它似乎是无限制和限制性的熵，相对熵或共同数据，并且在信息理论中发现了许多应用。在Renyi的论点中，黑洞熵的区域定律起着重要作用。但是，总熵可以通过系统的随机性来改变一些量子效应。在本说明中，通过采用这种修改后的熵关系，我们对牛顿的重力定律进行了更正。考虑到与弗里德曼·罗伯逊 - 沃克宇宙的明显视野相关的熵，并假定了热力学的第一定律，de = tds+wdv满足了明显的视野，我们重新考虑了扩展的宇宙并找到了修改的弗里德曼方程。此外，已经检查了第二种热力学定律。
The Renyi entropy coprises a group of data estimates that sums up the well-known Shannon entropy, acquiring a considerable lot of its properties. It appears as unqualified and restrictive entropy, relative entropy, or common data, and has found numerous applications in information theory. in the Renyi's argument, the area law of the black hole entropy plays a significant role. However, the total entropy can be modified by some quantum effects, motivated by the randomness of a system. In this note, by employing this modified entropy relation, we have derived corrections to Newton's law of gravitation. Taking this entropy associated with the apparent horizon of the Friedmann-Robertson-Walker Universe and assuming the first law of thermodynamics, dE=TdS+WdV, satisfies the apparent horizon, we have reconsidered expanding Universe and find modified Friedmann equations. Also, the second thermodynamics law has been examined.
