报告摘要:Einstein-Bogomol’nyi metrics, which physically models the Cosmic Strings, solves the Einstein’s Fields Equation coupled with an Abelian gauge field and a Higgs field.  In this talk, I will present a general existence theorem for Einstein-Bogomol’nyi metrics on Riemann sphere. I will also discuss the behaviors of the metrics as the volume approaches the lower bound and infinity respectively. Part of this talk is based on the joint work with Garcia-Fernandez and Pingali.
