Rotational Perturbations of High Density Matter in the Brane Cosmology
Chiang-Mei Chen, T. Harko, W. F. Kao +1
We consider the evolution of small rotational perturbations, with azimuthal symmetry, of the brane-world cosmological models. The equations describing the temporal, radial, and ang…
Rotational Perturbations of Friedmann-Robertson-Walker Type Brane-World Cosmological Models
Chiang-Mei Chen, T. Harko, W. F. Kao +1
First order rotational perturbations of the Friedmann-Robertson-Walker metric are considered in the framework of the brane-world cosmological models. A rotation equation, relating…
On Analytic Properties of the Photon Polarization Function in a Background Magnetic Field
W. F. Kao, G. -L. Lin, J. -J. Tseng
We examine the analytic properties of the photon polarization function in a background magnetic field, using the technique of inverse Mellin transform. The photon polarization func…
Bianchi type I space and the stability of inflationary Friedmann-Robertson-Walker space
W. F. Kao
Stability analysis of the Bianchi type I universe in pure gravity theory is studied in details. We first derive the non-redundant field equation of the system by introducing the ge…
Stability Analysis of Anisotropic Inflationary Cosmology
Chiang-Mei Chen, W. F. Kao
The stability analysis of an anisotropic inflationary universe of the four dimensional Neveu-Schwarz--Neveu-Schwarz string model with a nonvanishing cosmological constant is discus…
A new look at the pair-production width in a strong magnetic field
W. F. Kao, Guey-Lin Lin, Jie-Jun Tseng
We reexamine the process in a background magnetic field comparable to . This process is known to be non-perturbative in the magnetic-field streng…
