On initial conditions and global existence for accelerating cosmologies from string theory
Makoto Narita
We construct a solution satisfying initial conditions for accelerating cosmologies from string/M-theory. Gowdy symmetric spacetimes with a positive potential are considered. Also,…

Global properties of higher-dimensional cosmological spacetimes
Makoto Narita
We study global existence problems and asymptotic behavior of higher-dimensional inhomogeneous spacetimes with a compact Cauchy surface in the Einstein-Maxwell-dilaton (EMD) system…

Global existence problem in -Gowdy symmetric IIB superstring cosmology
Makoto Narita
We show global existence theorems for Gowdy symmetric spacetimes with type IIB stringy matter. The areal and constant mean curvature time coordinates are used. Before coming to tha…
