On the spectral moment of quasi-trees
The notion of \(S\)-order of graphs has been studied, but few results are available. The characterizations of the first and the last graphs, in an \(S\)-order, of all trees, all unicyclic graphs with given girth, unicyclic graphs and bicyclic graphs are known, respectively. The paper determines the last and the second last quasi-tree, in an \(S\)-order, in the set, respectively.
