Maximum Zagreb index, minimum hyper-Wiener index and graph connectivity

open access: yesApplied Mathematics Letters, 2009
AbstractIn this work we show that among all n-vertex graphs with edge or vertex connectivity k, the graph G=Kk∨(K1+Kn−k−1), the join of Kk, the complete graph on k vertices, with the disjoint union of K1 and Kn−k−1, is the unique graph with maximum sum of squares of vertex degrees.

The edge-Wiener index and the edge-hyper-Wiener index of phenylenes [PDF]

open access: yesDiscrete Applied Mathematics, 2019
Besides the well known Wiener index, which sums up the distances between all the pairs of vertices, and the hyper-Wiener index, which includes also the squares of distances, the edge versions of both indices attracted a lot of attention in the recent years.

On the Steiner hyper-Wiener index of a graph [PDF]

open access: yesApplied Mathematics and Computation, 2018
In this paper, we study the Steiner hyper-Wiener index of a graph, which is obtained from the standard hyper-Wiener index by replacing the classical graph distance with the Steiner distance. It is shown how this index is related to the Steiner Hosoya polynomial, which generalizes similar result for the standard hyper-Wiener index. Next, we show how the

Phanerozoic Large Igneous Province, Petroleum System, and Source Rock Links

open access: yesGeophysical Monograph Series, Page 191-228., 2021

Exploring the links between Large Igneous Provinces and dramatic environmental impact

An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Distance-Based Polynomials and Topological Indices for Hierarchical Hypercube Networks

open access: yesJournal of Mathematics, 2021
Topological indices are the numbers associated with the graphs of chemical compounds/networks that help us to understand their properties. The aim of this paper is to compute topological indices for the hierarchical hypercube networks. We computed Hosoya

Topological Indices of Graphs from Vector Spaces

open access: yesMathematics, 2023
Topological indices are numbers that are applied to a graph and can be used to describe specific graph properties through algebraic structures. Algebraic graph theory is a helpful tool in a range of chemistry domains.

GTI-space : the space of generalized topological indices [PDF]

open access: yes, 2008
A new extension of the generalized topological indices (GTI) approach is carried out torepresent 'simple' and 'composite' topological indices (TIs) in an unified way.
