Zagreb Degree Eccentricity Indices of Graphs
Abstract: AbstractLet G be a connected graph, the first Zagreb index M1(G) of G is defined as The second Zagreb index M2(G) of G is defined as In this paper we introduce first and second Zagreb degree eccentricity indices. Further, the first Zagreb degree eccentricity index of join, Cartesian product, tensor product, corona product of two graphs are computed. Keywords: Zagreb indices, Eccentricity, Degree, Zagreb degree eccentricity indices. Cite this ArticlePadmapriya …

Downhill Zagreb Polynomials of Graphs
Abstract: AbstractIn a number of applied and theoretical environments, graph polynomials and their roots have emerged. To deeply explore counting sequences connected to different graph parameters, graph polynomials have been introduced as generating polynomials. In addition, there has been a great deal of recent interest in graph polynomials. The first, second and forgotten downhill Zagreb indices are defined as and . In this paper, we define and study the first, second …

Graph Theoretic Analysis of Cyclodextrin Polymers
Abstract: Topological indicators in chemical graph theory are essential tools in cheminformatics, providing valuable insights into molecular structure and properties to make more accurate predictions about the behavior and efficacy of novel compounds in drug design. The macro molecules are correlated with certain derivatives. The derivatives are growing structures which depends on the cyclic structures. The Cyclodextrin is one of the cyclic structures which depends on the carbon atoms. The polymer …

Regression Analysis of Topological Indices and Physicochemical Properties of Polymer-Based Anticancer Drugs
Abstract: The research analyzed the quantitative correlation between topological indices and the physicochemical properties of selected anticancer compounds using regression analysis. Various topological descriptors—such as the First Zagreb Index, Second Zagreb Index, and Forgotten Index were calculated and regressed against key molecular features, including polar surface area, melting point, and molar refractivity. The regression analysis revealed linear correlations between these topological indices and the properties of anticancer drugs, with particularly strong …
