当平移对称在基态破缺时，有序介质缺陷的同伦理论必须补充来自叶理理论的可积性条件。这些显示了一些同伦类如何分裂成几个不同的缺陷，而其他同伦类并没有物理发生。这个框架也可以用来讨论规范场的缺陷，其中在第一近似中，分类空间扮演着内部态流形的角色。
When translational symmetry is broken in the ground state, the homotopy theory of defects of ordered media has to be supplemented with integrability conditions, coming from the theory of foliations. These show how some homotopy classes split into several distinct defects, while other homotopy classes do not occur physically. This framework can also be used in order to discuss defects of gauge fields, where in a first approximation classifying spaces play the role of the manifolds of internal states.
