报告题目:The anti-adjacency matrix of a graph: Eccentricity matrix

报告时间:2019年1月16日(周三)8:30-9:10

报告地点:静远楼204报告厅

报告摘要:

 In this talk, we introduce a new graph matrix,named the anti-adjacency matrix or eccentricity matrix, which is constructed from the distance matrix of a graph by keeping for each row and each columnonly the largest distances. This matrix can be interpreted as the opposite of the adjacency matrix, which is instead constructed from the distance matrix of a graph by keeping for each row and each column only the distance sequal to 1. Some results of the eigenvalues of the eccentricity matrices will be given.
