Area-law versus Rényi and Tsallis black hole entropies

S Nojiri, SD Odintsov, V Faraoni - Physical Review D, 2021 - APS
The Rényi and Tsallis entropies are discussed as possible alternatives to the Bekenstein-
Hawking area-law entropy. It is pointed out how replacing the entropy notion, but not the …
