The warped product approach to magnetically charged GMGHS spacetime
arXiv:1407.6428 · doi:10.1142/S0217732314501983
Abstract
In the framework of Lorentzian multiply warped products we study the magnetically charged Gibbons-Maeda-Garfinkle-Horowitz-Strominger (GMGHS) interior spacetime in the string frame. We also investigate geodesic motion in various hypersurfaces, and compare their solutions of geodesic equations with the ones obtained in the Einstein frame.
