Testing the quality of molecular structure descriptors. Vertex-degree-based topological indices [PDF]
Journal of the Serbian Chemical Society, 2013 The correlation ability of 20 vertex-degree-based topological indices, occurring in the chemical literature, is tested for the case of standard heats of formation and normal boiling points of octane isomers. It is found that the correlation ability of

On Distance-Based Topological Descriptors of Subdivision Vertex-Edge Join of Three Graphs
IEEE Access, 2019 The analysis of networks and graphs through topological descriptors carries out a useful role to derive their underlying topologies. This process has been widely used in biomedicine, cheminformatics, and bioinformatics, where assessments based on graph ...

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

Efficient Representation of Computational Meshes [PDF]
, 2007 We present a simple yet general and efficient approach to representation of computational meshes. Meshes are represented as sets of mesh entities of different topological dimensions and their incidence relations.

Journal of Mathematics, 2021 Vertices and edges are made from a network, with the degree of a vertex referring to the number of connected edges. The chance of every vertex possessing a given degree is represented by a network’s degree appropriation, which reveals important global ...

Some Vertex/Edge-Degree-Based Topological Indices of r-Apex Trees
Journal of Mathematics, 2021 In chemical graph theory, graph invariants are usually referred to as topological indices. For a graph G, its vertex-degree-based topological indices of the form BIDG=∑uv∈EGβdu,dv are known as bond incident degree indices, where EG is the edge set of G ...

On Zagreb coindices and Mostar index of $$TiO_2$$ T i O 2 nanotubes
Scientific Reports, 2023 Topological indices are valuable tools in predicting properties of chemical compounds. This study focuses on degree-based topological indices, which have shown strong correlations with various physico-chemical properties such as boiling points and strain

3-manifold groups are virtually residually p [PDF]
, 2012 Given a prime $p$, a group is called residually $p$ if the intersection of its $p$-power index normal subgroups is trivial. A group is called virtually residually $p$ if it has a finite index subgroup which is residually $p$.

Generalized Zagreb index of some dendrimer structures
Universal Journal of Mathematics and Applications, 2018 Chemical graph theory, is a branch of mathematical chemistry which deals with the nontrivial applications of graph theory to solve molecular problem. A chemical graph is represent a molecule by considering the atoms as the vertices and bonds between them

Information indices with high discriminative power for graphs. [PDF]
PLoS ONE, 2012 In this paper, we evaluate the uniqueness of several information-theoretic measures for graphs based on so-called information functionals and compare the results with other information indices and non-information-theoretic measures such as the well-known
