On the Existence of Turning Points in D-dimensionsal Schwarzschild-de Sitter and Anti-de Sitter Spacetimes
نویسنده
چکیده
We investigate the motion of a test particle in a d-dimensional, spherically symmetric and static space-time supported by a mass M plus a Λ-term. The motion is strongly dependent on the sign of Λ. In Schwarzschild-de Sitter (SdS) space-time (Λ > 0), besides the physical singularity at r = 0 there are cases with two horizons and two turning points, one horizon and one turning point and the complete absence of horizon and turning points. For Schwarzschild-Anti de Sitter (SAdS) space-time (Λ < 0) the horizon coordinate is associated to a unique turning point. [email protected] [email protected], [email protected] 1

Spacelike hypersurfaces with constant $S$ or $K$ in de Sitter space or anti-de Sitter space
Let $M^n$ be an $n(ngeq 3)$-dimensional complete connected and oriented spacelike hypersurface in a de Sitter space or an anti-de Sitter space, $S$ and $K$ be the squared norm of the second fundamental form and Gauss-Kronecker curvature of $M^n$. If $S$ or $K$ is constant, nonzero and $M^n$ has two distinct principal curvatures one of which is simple, we obtain some charact...
متن کاملSuper algebra and Harmonic Oscillator in Anti de Sitter space
The harmonic oscillator in anti de Sitter space(AdS) is discussed. We consider the harmonic oscillator potential and then time independent Schrodinger equation in AdS space. Then we apply the supersymmetric Quantum Mechanics approach to solve our differential equation. In this paper we have solved Schrodinger equation for harmonic oscillator in AdS spacetime by supersymmetry approach. The shape...

متن کاملOn the Classification of Asymptotic Quasinormal Frequencies for d–Dimensional Black Holes and Quantum Gravity
We provide a complete classification of asymptotic quasinormal frequencies for static, spherically symmetric black hole spacetimes in d dimensions. This includes all possible types of gravitational perturbations (tensor, vector and scalar type) as described by the Ishibashi–Kodama master equations. The frequencies for Schwarzschild are dimension independent, while for Reissner–Nordstrøm are dim...
