Lectures on Cosmic Topological Defects
arXiv:hep-ph/0101270
Abstract
These lectures review certain topological defects and aspects of their cosmology. Unconventional material includes brief descriptions of electroweak defects, the structure of domain walls in non-Abelian theories, and the spectrum of magnetic monopoles in SU(5) Grand Unified theory.
34 pages; lectures at the 2000 summer school in cosmology at ICTP, Trieste; minor correction in domain wall section
