GENERAL RELATIVITY AND GRAVITATION

چکیده
|
Using the Sharma-Mittal entropy, we study some properties of the
Schwarzschild and Schwarzschild-de Sitter black holes. The results
are compared with those obtained by attributing the Bekenstein
entropy bound to the mentioned black holes. Our main results show
that while the Schwarzschild black hole is always stable in the
micro-canonical ensemble, it can be stable in the canonical
ensemble if its mass is bigger than the mass of the coldest
Schwarzschild black hole. A semi-classical analysis has also been
used to find an approximate relation between the entropy free
parameters. Throughout the paper, we use units $c=G=\hbar=k_B=1$,
where $k_B$ denotes the Boltzmann constant.
