研究了自发破缺规范理论中宇宙中可能出现的磁区结构。结果表明，磁区壁、弦或单极子的形成取决于简并真空流形的同伦群。对这些结构的后续演化进行了研究。有人认为，虽然产生域壁的理论可能会被消除(因为它们不可接受的引力效应)，但一个由弦组成的宇宙网络很可能已经形成，并可能具有重要的宇宙学效应。
The possible domain structures which can arise in the universe in a spontaneously broken gauge theory are studied. It is shown that the formation of domain wall, strings or monopoles depends on the homotopy groups of the manifold of degenerate vacua. The subsequent evolution of these structures is investigated. It is argued that while theories generating domain walls can probably be eliminated (because of their unacceptable gravitational effects), a cosmic network of strings may well have been formed and may have had important cosmological effects.
