Solution Independent Analysis of Black Hole Entropy in Brick Wall Model
M. Kenmoku, K. K. Nandi, K. Shigemoto
Using the brick wall regularization of 't Hooft, the entropy of non-extreme and extreme black holes is investigated in a general static, spherically symmetric spacetime. We classif…

Conservation of Energy in Black Holes and in Cosmology
M. Kenmoku, K. Shigemoto
We first review the various definition of the total energy in the gravitational system. The naive definition has some defects, and we review how to modify the definition of the tot…

Star-Triangle Relation of the Chiral Potts Model Revisited
M. Horibe, K. Shigemoto
We give the simple proof of the star-triangle relation of the chiral Potts model. We also give the constructive way to understand the star-triangle relation of the chiral Potts mod…
