The No-defect Conjecture: Cosmological Implications

General Relativity and Quantum Cosmology 2008-11-26 v1

Abstract

When the topology of the universe is non trivial, it has been shown that there are constraints on the network of domain walls, cosmic strings and monopoles. I generalize these results to textures and study the cosmological implications of such constraints. I conclude that a large class of multi-connected universes with topological defects accounting for structure formation are ruled out by observation of the cosmic microwave background.
