Spectra of unicyclic graphs

Graphs and Combinatorics, 1987
We study lexicographic ordering of unicyclic graphs by spectral moments as well as the ordering by the largest eigenvalue. If the length of the cycle is fixed, extremal graphs in the first ordering are obtained by attaching a star and a path to a cycle. For the other ordering minimal graphs are not known.

THE GUTMAN INDEX OF UNICYCLIC GRAPHS

Discrete Mathematics, Algorithms and Applications, 2012
Let G be a connected graph with vertex set V(G). The Gutman index of G is defined as S(G) = ∑{u, v}⊆V(G) d(u)d(v)d(u, v), where d(u) is the degree of vertex u, and d(u, v) denotes the distance between u and v. In this paper, we characterize n-vertex unicyclic graphs with girth k, having minimal Gutman index.
