Shrabani Das, Rajat Kanti Nath, Yilun Shang

TL;DR
This paper computes Zagreb indices for commuting conjugacy class graphs of finite groups and verifies the Hansen-Vuki{ extbackslash}cevi{ extbackslash}c conjecture for various classes of these graphs, including dihedral and Frobenius groups.
Contribution
It extends the verification of the Hansen-Vuki{ extbackslash}cevi{ extbackslash}c conjecture to new classes of finite groups via their commuting conjugacy class graphs.
Findings
Hansen-Vuki{ extbackslash}cevi{ extbackslash}c conjecture holds for dihedral, dicyclic, and semidihedral groups.
The conjecture is verified for groups with specific quotient structures like $D_{2m}$ and Frobenius groups.
Computed Zagreb indices support the conjecture across multiple finite group classes.
Abstract
In this work, we compute the first and second Zagreb indices for the commuting conjugacy class graphs associated with finite groups. We identify multiple classes of finite groups whose commuting conjugacy class graphs are shown to satisfy the Hansen-Vuki{\v{c}}evi{\'c} conjecture. Specifically, we prove that the conjecture holds for the commuting conjugacy class graphs of dihedral groups (), dicyclic groups, semidihedral groups, and various other two-generator groups. Moreover, we examine the case where the quotient is isomorphic to , , a Frobenius group of order or , or any group of order , for primes and . In each of these cases, we demonstrate that the corresponding commuting conjugacy class graph satisfies the Hansen-Vuki{\v{c}}evi{\'c} conjecture.
