Nonsingular static global string

TL;DR

This paper presents the first example of a nonsingular spacetime solution around a static global string, improving the understanding of such cosmic structures by eliminating singularities.

Contribution

It introduces a novel nonsingular spacetime solution for the exterior of a static global string, which was not previously known.

Findings

First nonsingular spacetime around a static global string

Provides a new model for cosmic string spacetimes

Enhances theoretical understanding of global string properties

Abstract

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.}}
