Cosmological constant and curved 5D geometry
Masato Ito
We study the value of cosmological constant in de Sitter brane embedded in five dimensions with positive, vanishing and negative bulk cosmological constant. In the case of negative…

Linearized gravity in flat braneworlds with anisotropic brane tension
Masato Ito
We study the four-dimensional gravitational fluctuation on anisotropic brane tension embedded in braneworlds with vanishing bulk cosmological constant. In this setup, warp factors…

Five-Dimensional Warped Geometry with a Bulk Scalar Field
Masato Ito
We explore the diversity of warped metric function in five-dimensional gravity including a scalar field and a 3-brane. We point out that the form of the function is determined by a…
