A STUDY OF GLOBAL STRING IN LYRA GEOMETRY

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