计算双路图的亏格分布是拓扑图论关注的一个问题,利用传递矩阵与向量积矩阵,给出了两类由双路图串联构建而成的两类闭链图的亏格分布.

英文摘要：

Calculating the genus distributions of double-path graphs is a concerned topic in topological graph theory. In this paper, by using transfer matrix method and a vectorized production matrix, the calculation formulas for the genus distributions of two types of graphs formed by double-path connect in series are derived.
