Resumo: Graphs with few distinct eigenvalues, according to Brower and Hammers, are important because they have some kind of regularity. This means that the number of distinct eigenvalues, considering matrices associated with a graph, is intrinsically related to the structure of the graph. In this talk we will present some classes of graphs with few distinct eigenvalues, considering the Distance matrix and the Laplacian Distance matrix. We will investigate some structural properties in these classes, such as forbidden subgraphs.
