Bounds and extremal graphs of second reformulated Zagreb index for graphs with cyclomatic number at most three [PDF]

open access: yesKuwait Journal of Science, 2021
Mili\v{c}evi\'{c} \textit{et al.}, in 2004, introduced topological indices known as Reformulated Zagreb indices, where they modified Zagreb indices using the edge-degree instead of vertex degree.

On the Reformulated Second Zagreb Index of Graph Operations [PDF]

open access: yesJournal of Chemistry, 2021
Topological indices (TIs) are expressed by constant real numbers that reveal the structure of the graphs in QSAR/QSPR investigation. The reformulated second Zagreb index (RSZI) is such a novel TI having good correlations with various physical attributes,

On the Reformulated Multiplicative First Zagreb Index of Trees and Unicyclic Graphs [PDF]

open access: yesDiscrete Dynamics in Nature and Society, 2021
The multiplicative first Zagreb index of a graph H is defined as the product of the squares of the degrees of vertices of H. The line graph of a graph H is denoted by LH and is defined as the graph whose vertex set is the edge set of H where two vertices

Reformulated First Zagreb Index of Some Graph Operations [PDF]

open access: yesMathematics, 2015
The reformulated Zagreb indices of a graph are obtained from the classical Zagreb indices by replacing vertex degrees with edge degrees, where the degree of an edge is taken as the sum of degrees of the end vertices of the edge minus 2. In this paper, we

Degree-Based Topological Indices of Generalized Subdivision Double-Corona Product

open access: yesJournal of Chemistry, 2022
Graph operations play an important role in constructing complex network structures from simple graphs. Computation of topological indices of these complex structures via graph products is an important task.

European guideline on obesity care in patients with gastrointestinal and liver diseases - Joint European Society for Clinical Nutrition and Metabolism / United European Gastroenterology guideline. [PDF]

open access: yesUnited European Gastroenterol J, 2022
Abstract Background Patients with chronic gastrointestinal (GI) disease such as inflammatory bowel disease (IBD), irritable bowel syndrome (IBS), celiac disease, gastroesophageal reflux disease (GERD), pancreatitis, and chronic liver disease (CLD) often suffer from obesity because of coincidence (IBD, IBS, celiac disease) or related pathophysiology ...

Two Complex Graph Operations and their Exact Formulations on Topological Properties

open access: yesComplexity, 2022
Graph operations are utilized for developing complicated graph structures from basic graphs, and these basic graphs can help to understand the properties of complex networks. While on the other side, the topological descriptor is known as a numeric value

Four new operations related to composition and their reformulated Zagreb index

open access: yesIndonesian Journal of Combinatorics, 2018
The first reformulated Zagreb index EM1(G) of a simple graph G is defined as the sum of the terms (du+dv-2)2 over all edges uv of G. In 2017, Sarala et al. introduced four new operations (F-product) of graphs.
