报告题目：Spectra of graphs under an operation

报告摘要：In this talk, I will introduce a new operation on graphs and the way to obtained the spectrum of the resultant graph. The result is used to obtain the spectrum of a linear hexagon. Most importantly, the proof of the main result involves a new technique. An iterative result is used to obtain the characteristic polynomial of the adjacency matrix of the resultant graph.
