The matrix representations of hypergraphs have been defined via hypermatrices initially. In recent studies, the Laplacian hypergraphs, a generalization matrix, has introduced. this article, based on definition, we derive bounds depending pair-degree, maximum degree, and first Zagreb index for greatest eigenvalue energy r-uniform regular hypergraphs. As result these bounds, Nordhaus–Gaddum type ...

A topological descriptor is regarded as a numerical parameter derived by using mathematical tools from the molecular graph of different chemical structures. The theory paramount section chemistry. In this section, there are many parameters, that have very useful characteristics to study structure chemicals. article, we investigate indices concealed non-kekulean benzenoid hydrocarbon graph. We w...

We study eccentricity-based indices such as Zagreb eccentricity indices, general index and total index. present exact values of generalized networks related to binary $m$-ary trees, where $m \ge 2$.

A topological index, which is a number, connected to graph. It often used in chemometrics, biomedicine, and bioinformatics anticipate various physicochemical properties biological activities of compounds. The purpose this article encourage original research focused on graph indices for the drugs azacitidine, decitabine, guadecitabine as well an investigation genesis symmetry actual networks. Sy...

AIM To investigate the prevalence of dental caries and treatment needs in schoolchildren aged 7-14 years from Zagreb. METHODS Dental examinations based on the World Health Organization criteria were performed on 1168 children in the period 2009-2010. The teeth were clinically examined with standard dental instruments using visual-tactile method under standard dental light. We recorded the cli...
