Nonsingular static global string
A new solution for the spacetime outside the core of a U (1) static global string has been presented which is nonsingular. This is the first example of a nonsingular spacetime around a static global string. It is believed that early universe has undergone a number of phase transitions as it cooled down from the hot initial phase. One of the immediate consequences of these phase transitions is t...
متن کاملNonsingular global string compactifications
We consider an exotic "compactification" of spacetime in which there are two infinite extra dimensions, using a global string instead of a domain wall. By having a negative cosmological constant we prove the existence of a nonsingular static solution using a dynamical systems argument. A nonsingular solution also exists in the absence of a cosmological constant with a time-dependent metric. We ...
متن کاملNonsingular global strings.
We examine the possibility that time dependence might remove the singular nature of global string spacetimes. We first show that this time dependence takes a specific form – a de-Sitter like expansion along the length of the string and give an argument for the existence of such a solution, estimating the rate of expansion. We compare our solution to the singular Cohen-Kaplan spacetime. PACS num...
متن کاملNonsingular Dilaton Cosmology in the String Frame
One of the paramount problems manifest in modern cosmological theories is that of the initial singularity. Gasperini and Veneziano have proposed the pre-big-bang (PBB) model [2] based on the assumption that the Universe evolved out of a ten-dimensional Minkowski spacetime which is an exact vacuum of string theory, in hopes of resolving the singularity problem. Recently, Brandenberger, Easther a...
متن کاملSelf-Gravitating Global Monopole and Nonsingular Cosmology
We review some recent results concerning the properties of a spherically symmetric global monopole in (D = d+2)-dimensional general relativity. Some common features of monopole solutions are found independently of the choice of the symmetry-breaking potential. Thus, the solutions show six types of qualitative behavior and can contain at most one simple horizon. For the standard Mexican hat (Hig...
