Comment on Entropy in Two-dimensional Dilaton Gravity
Kouichirou Hirata, Yoshi Fujiwara, Jiro Soda
The thermodynamic second law in the evaporating black hole space-time is examined in the context of two-dimensional dilaton black hole. The dynamical evolution of entropy is invest…

Wavelet Analysis of One-Dimensional Cosmological Density Fluctuations
Yoshi Fujiwara, Jiro Soda
Wavelet analysis is proposed as a new tool for studying the large-scale structure formation of the universe. To reveal its usefulness, the wavelet decomposition of one-dimensional…

Does a domain wall emit gravitational waves? -- General-relativistic perturbative treatment
Hideo Kodama, Hideki Ishihara, Yoshihisa Fujiwara
The behavior of gravitational wave perturbations on a locally Minkowskian spacetime background containing a planar domain wall is investigated in the gauge-invariant general relati…
