M. Axenides et al., CORE PHASE-STRUCTURE OF COSMIC STRINGS AND MONOPOLES - ART. NO. 103512, Physical review. D. Particles and fields, 5810(10), 1998, pp. 3512
Global and local symmetries may or may not be restored inside topologi
cal defects depending upon the values of the parameters of the model.
A detailed study of this parameter dependence of the core structure of
strings and monopoles is presented in the context of simple models. [
