On the spectral radius of atom-bond maximum degree-based sum-connectivity matrix and its applications as molecular descriptors

Kuwait Journal of Science
matrices have been extensively studied. One of the modified versions of Randić index is the index 𝑅′ (𝐺) = ∑ 𝑣𝑖∼𝑣𝑗 1 / max{𝑑𝑖 , 𝑑𝑗 } , where 𝑑𝑖 and 𝑑𝑗 are the vertex degrees of 𝑣𝑖 and 𝑣𝑗 , respectively.

Zonal Labeling of Graphs

Indonesian Journal of Combinatorics
A planar graph is said to be zonal when is possible to label its vertices with the nonzero elements of ℤ3, in such a way that the sum of the labels of the vertices on the boundary of each zone is 0 in ℤ3.

The Chromatic Symmetric Function for Unicyclic Graphs

Motivated by the question of which structural properties of a graph can be recovered from the chromatic symmetric function (CSF), we study the CSF of connected unicyclic graphs. While it is known that there can be non-isomorphic unicyclic graphs with the

The smallest Hosoya index of unicyclic graphs with given diameter [PDF]

, 2012
The Hosoya index of a (molecular) graph is defined as the total number of the matchings, including the empty edge set, of this graph. Let ${\cal{U}}_{n,d}$ be the set of connected unicyclic (molecular) graphs of order n with diameter d. In this paper we
