Asymptotically anti-de Sitter spacetimes and conserved quantities in higher curvature gravitational theories
Naoya Okuyama, Jun-ichirou Koga
We consider -dimensional asymptotically anti-de Sitter spacetimes in higher curvature gravitational theories with , by employing the conformal completion technique. We…
Domain Wall Dynamics in Brane World and Non-singular Cosmological Models
Naoya Okuyama, Kei-ichi Maeda
We study brane cosmology as 4D (4-dimensional) domain wall dynamics in 5D bulk spacetime. For a generic 5D bulk with 3D maximal symmetry, we derive the equation of motion of a doma…
A Classification of Spherically Symmetric Kinematic Self-Similar Perfect-Fluid Solutions. II
Hideki Maeda, Tomohiro Harada, Hideo Iguchi +1
We give a classification of spherically symmetric kinematic self-similar solutions. This classification is complementary to that given in a previous work by the present authors [Pr…
Five-dimensional Black Hole and Particle Solution with Non-Abelian Gauge Field
Naoya Okuyama, Kei-ichi Maeda
We study the 5-dimensional Einstein-Yang-Mills system with a cosmological constant. Assuming a spherically symmetric spacetime, we find a new analytic black hole solution, which ap…
A Classification of Spherically Symmetric Kinematic Self-Similar Perfect-Fluid Solutions
Hideki Maeda, Tomohiro Harada, Hideo Iguchi +1
We classify all spherically symmetric spacetimes admitting a kinematic self-similar vector of the second, zeroth or infinite kind. We assume that the perfect fluid obeys either a p…
No Go Theorem for Kinematic Self-Similarity with A Polytropic Equation of State
Hideki Maeda, Tomohiro Harada, Hideo Iguchi +1
We have investigated spherically symmetric spacetimes which contain a perfect fluid obeying the polytropic equation of state and admit a kinematic self-similar vector of the second…
