Ordering Unicyclic Graphs in Terms of Their Smaller Least Eigenvalues
Let be a simple graph with vertices, and let be the least eigenvalue of . The connected graphs in which the number of edges equals the number of vertices are called unicyclic graphs.

The inertia of unicyclic graphs and bicyclic graphs
Let G be a graph with n vertices and (G) be the matching number of G. The inertia of a graph G, In(G) = (n+;n ;n0) is an integer triple specifying the numbers of positive, negative and zero eigenvalues of the adjacency matrix A(G), respectively. Let (G) = n0 denote the nullity of G (the multiplicity of the eigenvalue zero of G).

The minimum matching energy of unicyclic graphs with fixed number of vertices of degree two
The number of jj-matchings in a graph HH is denote by m(H,j)m\left(H,j). If for two graphs H1{H}_{1} and H2{H}_{2}, m(H1,j)≥m(H2,j)m\left({H}_{1},j)\ge m\left({H}_{2},j) for all jj, then we write H1≽H2{H}_{1}\succcurlyeq {H}_{2}.

The largest n - 1 Hosoya indices of unicyclic graphs
The Hosoya index Z(G) of a graph G is defined as the total number of edge independent sets of G. In this paper, we extend the research of [J. Ou, On extremal unicyclic molecular graphs with maximal Hosoya index, Discrete Appl. Math.
