Abstract

An exact solution for the space-time outside the core of a U(1) static global string in Lyra geometry is presented. Our global string is nonsingular at a finite distance from the string core. The gravitational field of the global string is shown to be attractive in nature.

Keywords

Global string; Lyra geometry; gravitational field
