Cosmic strings in axionic-dilatonic gravity
arXiv:gr-qc/0009102 · doi:10.1088/0264-9381/18/10/302
Abstract
We first consider local cosmic strings in dilaton-axion gravity and show that they are singular solutions. Then we take a supermassive Higgs limit and present expressions for the fields at far distances from the core by applying a Pecci-Quinn and a duality transformation to the dilatonic Melvin's magnetic universe.
