Some inequalities on the norms of special matrices with generalized Tribonacci and generalized Pell Padovan sequences
Zahid Raza, Muhammad Riaz, Muhammad Asim Ali
In this paper some properties of generalized tribonacci and generalized Padovan sequence are presented. Also the Euclidean norms of circulant, -circulant, semi-circulant and Han…
On the Augmented Zagreb Index
Akbar Ali, Zahid Raza, Akhlaq Ahmad Bhatti
Topological indices play an important role in mathematical chemistry especially in the quantitative structure-property relationship (QSPR) and quantitative structure-activity relat…
Further Inequalities Between Vertex-Degree-Based Topological Indices
Akbar Ali, Akhlaq Ahmad Bhatti, Zahid Raza
Continuing the recent work of L. Zhong and K. Xu [MATCH Commun. Math. Comput. Chem.71(2014) 627-642], we determine inequalities among several vertex-degree-based topological indice…
More on Comparison Between First Geometric-Arithmetic Index and Atom-Bond Connectivity Index
Zahid Raza, Akhlaq Ahmad Bhatti, Akbar Ali
The first geometric-arithmetic (GA) index and atom-bond connectivity (ABC) index are molecular structure descriptors which play a significant role in quantitative structure-propert…
