带符号图是每条边都附有符号的图。本文将拉普拉斯矩阵的一些基本概念从图扩展到符号图。特别是，研究了有符号图的最大拉普拉斯特征值，这将相应的结果推广到图的最大拉普拉斯特征值上。
A signed graph is a graph with a sign attached to each edge. This article extends some fundamental concepts of the Laplacian matrices from graphs to signed graphs. In particular, the largest Laplacian eigenvalue of a signed graph is investigated, which generalizes the corresponding results on the largest Laplacian eigenvalue of a graph.
