Gravitational energy, dS/CFT correspondence and cosmic no-hair
Tetsuya Shiromizu, Daisuke Ida, Takashi Torii
The gravitational energy is examined in asymptotically de Sitter space-times. The positivity will be shown for certain cases. The de Sitter/CFT(dS/CFT) correspondence recently prop…
The stability of the shell of D6-D2 branes in a supergravity solution
K. Maeda, T. Torii, M. Narita +1
The stability of the shell of wrapped D6-branes on K3 is investigated from the point of view of supergravity. We first construct an effective energy-momentum tensor for the shell u…
Stability of Compactifications
Tetsuya Shiromizu, Daisuke Ida, Hirotaka Ochiai +1
We examine the stability of . The initial data constructed by De Wolfe et al \cite{Gary} has been carefully analyised and we have…
Brane-World and Holography
Tetsuya Shiromizu, Takashi Torii, Daisuke Ida
We consider the brane-world in the holographic point of view. Bearing the realistic models in mind, the bulk massless scalar field is introduced. First of all, we find the constrai…
