我们提出了一个新的熵结构，它推广了Tsallis，Renyi，Sharma-Mittal，巴罗，Kaniadakis和圈量子引力熵，并在一定限度内约化为Bekenstein-Hawking熵。这个建议适用于史瓦西黑洞和空间均匀和各向同性的宇宙学，在那里它表明，它可以潜在地描述通货膨胀和/或全息暗能量。
We propose a new entropy construct that generalizes the Tsallis, Renyi, Sharma-Mittal, Barrow, Kaniadakis, and loop quantum gravity entropies and reduces to the Bekenstein-Hawking entropy in a certain limit. This proposal is applied to the Schwarzschild black hole and to spatially homogeneous and isotropic cosmology, where it is shown that it can potentially describe inflation and/or holographic dark energy.
