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…
On the existence of global solutions for -Gowdy spacetimes with stringy matter
Makoto Narita
We show a global existence theorem for Einstein-matter equations of -Gowdy symmetric spacetimes with stringy matter. The areal time coordinate is used. It is shown that this…
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…
The excitation of a charged string passing through a shock wave in a charged Aichelburg-Sexl spacetime
Kengo Maeda, Takashi Torii, Makoto Narita +1
We investigate how much a first-quantized charged bosonic test string gets excited after crossing a shock wave generated by a charged particle with mass and charge $\ti…
