Leap Indices and Their Polynomials of the Derived Graph of the Subdivision of Certain Polyphenyls
(Sami Publishing Co-spc, 2020) Asif, Fatima; Zahid, Zohaib; Farahani, Mohammad Reza; Cancan, Murat; Ediz, Suleyman
Topological indices are real (numerical) values which are associated with chemical compositions to correlate with chemical structure with different physical properties, chemical and biological activities. In this article, we computed and compared leap Zagreb indices and leap hyper-Zagreb indices of the derived graph of the subdivision of certain polyphenyls based on the 2-distance degree of the vertices.
On Sombor Indices of Line Graph of Silicate Carbide Si2c3-I[p,q]
(Taylor & Francis Ltd, 2022) Asif, Fatima; Zahid, Zohaib; Husin, Mohamad Nazri; Cancan, Murat; Tas, Ziyattin; Alaeiyan, Mehdi; Farahani, Moahmmad Reza
Topological indices are numerical parameters associated with underlying topology of a molecular structure. They are correlated with several physio-chemical properties of chemical compounds. Recently, Euclidean metric based topological index has been introduced named as Sombor index. Therefore, in this article, we will discuss combinatorial aspects and compute Sombor index, average Sombor index and the reduced Sombor index of line graph of silicate carbides Si2C3-I[p, q].
On Some Leap Indices of Polycyclic Aromatic Hydrocarbons (Pahs)
(Taru Publications, 2020) Asif, Fatima; Zahid, Zohaib; Cancan, Murat
Graph invariants are numerical values assigned to some molecular graph G(M) to characterize its topological properties. The second neighbourhood or a 2 -distance degree of any vertex v in a graph G(M) is the cardinality of its second neighbors. In this research article, we formulated some expressions for the leap Zagreb indices, leap hyper-indices and F - leap indices, depending on the second degree of a vertex, of a family of a molecular graph called Polycyclic Aromatic Hydrocarbons PAH(s).
