Unicyclic Graphs Satisfy Harary′s Conjecture

Canadian Mathematical Bulletin, 1974
Ulam in [7] has conjectured that any graph G with p≥3 nodes is uniquely reconstructable from its collection of subgraphs Gi=G-vi, i=1,2, … p. This conjecture has been proved for various finite graphs including regular, Eulerian, unicyclic, separable, trees and cacti.

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.

Vertex betweenness centrality of corona graphs and unicyclic graphs

2023
Summary: The idea of centrality measurements is quite appropriate for determining the important vertices or edges in a network. A vertex in a network may be an important vertex depending on its angle of assumption. There are many centrality measurements to find the characteristics of a vertex in a network. Betweenness centrality is an important variant
