Connectivity Index of Generalized Uncertain Graph [PDF]
Computational Intelligence and Neuroscience, 2022 In the application of classical graph theory, there always are various indeterministic factors. This study studies the indeterministic factors in the connected graph by employing the uncertainty theory. First, this study puts forward two concepts: generalized uncertain graph and its connectivity index. Second, it presents a new algorithm to compute the

A note on general sum-connectivity index
Proyecciones (Antofagasta), 2023 For a simple finite graph G, general sum-connectivity index is defined for any real number α as χα(G) = , which generalises both the first Zagreb index and the ordinary sum-connectivity index. In this paper, we present some new bounds for the general sum-connectivity index. We also present relation between general sum-connectivity index and general

On eccentric connectivity index
, 2010 The eccentric connectivity index, proposed by Sharma, Goswami and Madan, has been employed successfully for the development of numerous mathematical models for the prediction of biological activities of diverse nature. We now report mathematical properties of the eccentric connectivity index.

Filomat, 2011 The sum-connectivity index of a simple graph G is defined in mathematical chemistry as R+(G) = ? uv?E(G)(du+dv)?1/2, where E(G) is the edge set of G and du is the degree of vertex u in G. We give a best possible lower bound for the sum-connectivity index of a graph (a triangle-free graph, respectively) with n vertices and minimum degree at ...

Ordering of alkane isomers by means of connectivity indices [PDF]
Journal of the Serbian Chemical Society, 2002 The connectivity index of an organic molecule whose molecular graph is Gis defined as C(λ)=Σ(δuδv)λwhere δu is the degree of the vertex u in G, where the summation goes over all pairs of adjacent vertices of G and where λ is a pertinently chosen ...

New Dimensions of Connectivity in the Asia-Pacific [PDF]
, 2021 There is no bigger policy agenda in the East Asian region than connectivity. Costs of international connectivity are indeed falling, in the movement of goods, services, people and data, leading to greater flows, and to the reorganisation of business and ...

Exploring structural sediment connectivity via surface runoff in agricultural lands of Finland
Acta Agriculturae Scandinavica. Section B, Soil and Plant Science, 2022 Spatial information on the distribution of erosion areas and sediment transport pathways within agricultural landscapes is limited. Thus, we assess structural sediment connectivity via surface runoff by using a digital elevation model (2 × 2 m2) and ...

On the Edge-Connectivity of an Uncertain Random Graph
IEEE Access, 2020 Connectivity is one of the most important concepts in graph theory. When graph theory is applied to complex systems with indeterminate factors, uncertainty and randomness are two basic types of indeterminacy.
