论文摘要
混合的多编码是通过将其边缘的子集取向非方向的多编码的。在本文中，我们研究了混合多编码的新的Hermitian矩阵表示，介绍了混合多编码的COSECTRAL操作，并根据基本周期的基础来表征切换等效的混合多编码。作为一种应用，获得了具有相同基础图的混合多编码的上限。
A mixed multigraph is obtained from an undirected multigraph by orienting a subset of its edges. In this paper, we study a new Hermitian matrix representation of mixed multigraphs, give an introduction to cospectral operations on mixed multigraphs, and characterize switching equivalent mixed multigraphs in terms of fundamental cycle basis. As an application, an upper bound of cospectral classes of mixed multigraphs with the same underlying graph is obtained.
