Title: A glimpse of spectral graph theory

Abstract: Spectral graph theory is the study of the interplay between the spectrum of the adjacency matrix of a graph and the properties of the graph. We present a selection of results from spectral graph theory. These include a result on non-isomorphic cospectral trees, a problem on decomposing the complete graph on ten vertices by copies of the Petersen graph, and characterization of nonsingular trees. We conclude by presenting a path-breaking recent proof of the sensitivity conjecture by Huang.
