Topological indices are numeric values associated with a graph and characterize its structure. There various topological in theory such as degree-based, distance-based, counting-related indices. Among these indices, degree-based very interesting studied well literature. In this work, we the generalized form of harmonic, geometric-arithmetic, Kulli–Basava power-sum-connectivity index for special...

Starch is a polymer of glucose where alpha-linkages are associated with glucopyranose units. It comprises mixture amylose and amylopectin. Furthermore, linear chain hundreds molecules. Starches not allowed to be dissolved in water. They can digested by breaking down alpha bonds (glycosidic bonds). Its cyclic degradation products, called cyclodextrins, the best role models for amylose. considere...

One of the most recent developments in field graph theory is analysis networks such as Butterfly networks, Benes Interconnection and David-derived using theoretic parameters. The topological indices (TIs) have been widely used invariants among various tools. Quantitative structure activity relationships (QSAR) quantitative property (QSPR) need use TIs. Different structure-based parameters, degr...

it is well known that the chemical behavior of a compound is dependent upon the structure of itsmolecules. quantitative structure – activity relationship (qsar) studies and quantitative structure –property relationship (qspr) studies are active areas of chemical research that focus on the nature ofthis dependency. topological indices are the numerical value associated with chemical constitution...

The topological index is a numerical representation of molecular structure and predicts the physical property chemical compound. In present work, we have developed explicit expressions recently defined novel Ve- degrees Ev-degrees based indices Magnesium Oxide MgO (111). For this by consider unit cell (111) which extended to its general structure. After that, computed Ve-degrees then employing ...

Rev. Roum. Chim. (submitted). Abstract Similarity of two sets of cycle-containing molecular graphs: spiro-alkanes and full Hamiltonian detour cubic cages, is discussed in terms of interand intra-molecular similarity. Molecular description is given as sequences of some well known topological sequences: Distance Degree Sequence DDS, Detour Degree Sequence ∆DS, All Path Sequence APS, Shortest Path...

We obtain inequalities involving many topological indices in classical graph products by using the f-polynomial. In particular, we work with lexicographic product, Cartesian sum and first Zagreb, forgotten, inverse degree lordeg indices.
