给出了拓扑相间隙壁和拓扑相间隙边界的数学定义。然后，我们根据Davydov， m<s:1> ger， Nikshych和Ostrik的著作，回答了Lan， Wang和Wen最近在凝聚态物理中研究的一些问题。特别地，我们确定了它们的隧穿矩阵和一个Rehren的耦合矩阵，并证明了它们的猜想不成立。
We give a mathematical definition of a gapped domain wall between topological phases and a gapped boundary of a topological phase. We then provide answers to some recent questions studied by Lan, Wang and Wen in condensed matter physics based on works of Davydov, Müger, Nikshych and Ostrik. In particular, we identify their tunneling matrix and a coupling matrix of Rehren, and show that their conjecture does not hold.
