We use the Chern–Simons action for a [Formula: see text]-connection for the description of point disclinations in the geometric theory of defects. The most general spherically symmetric [Formula: see text]-connection with zero curvature is found. The corresponding orthogonal spherically symmetric [Formula: see text] matrix and [Formula: see text]-field are computed. Two examples of point disclinations are described.

Chern-Simons 缺陷几何理论中的点向错

我们使用 Chern-Simons 动作来描述缺陷几何理论中的点向错。找到了最一般的具有零曲率的球对称[公式：见正文]-连接。计算相应的正交球对称[公式：见文本]矩阵和[公式：见文本]域。描述了两个点向错的例子。
