Quantum entropy of two-dimensional extreme charged dilaton black hole
Bin Wang, Ru-Keng Su, P. K. N. Yu
By using Hawking's treatment as well as Zaslavskii's treatment respectively and the brick wall model, two different values of classical entropy and quantum entropy of scalar fields…

Can nonextremal Reissner-Nordstrom black hole become extremal by assimilating infalling charged particle and shell?
Bin Wang, Ru-Keng Su, P. K. N. Yu +1
By using the gedanken experiments suggested by Bekenstein and Rosenzweig, we have shown that nonextremal Reissner-Nordstrom black hole cannot turn into extremal one by assimilating…

Geometry of the extreme Kerr black holes
Bin Wang, Ru-Keng Su, P. K. N. Yu
Geometrical properties of the extreme Kerr black holes in the topological sectors of nonextreme and extreme configurations are studied. We find that the Euler characteristic plays…
