Noncommutative BTZ Black Hole in Polar Coordinates
Ee Chang-Young, Daeho Lee, Youngone Lee
Based on the equivalence between the three dimensional gravity and the Chern-Simons theory, we obtain a noncommutative BTZ black hole solution as a solution of $U(1,1)\times U(1,1)…
Cosmological Imprint of the Second Law of Thermodynamics
Hyeong-Chan Kim, Jae-Weon Lee, Jungjai Lee
We study the evolution of the universe in the presence of inflaton, matter, radiation, and holographic dark energy. The time evolution of the scale factor is obtained by solving th…
Geometrical properties of the trans-spherical solutions in higher dimensions
Gungwon Kang, Hyeong-Chan Kim, Jungjai Lee
We investigate the geometrical properties of static vacuum -brane solutions of Einstein gravity in dimensions, which have spherical symmetry of orthogonal to…
Extraordinary vacuum black string solutions
Hyeong-Chan Kim, Jungjai Lee
In addition to the boosted static solution there are two other classes of stationary string-like solutions of the vacuum Einstein equation in (4+1)-dimensions. Each class is charac…
Black string and velocity frame dragging
Jungjai Lee, Hyeong-Chan Kim
We investigate velocity frame dragging with the boosted Schwarzschild black string solution and the boosted Kaluza-Klein bubble solution, in which a translational symmetry along th…
Stationary vacuum hyper-cylindrical solution in 4+1 dimensions
Jungjai Lee, Hyeong-Chan Kim
We find a 4+1 dimensional stationary vacuum hyper-cylindrical solution solution which is spherically symmetric in dimensions and invariant under the translation along the fifth…
