Molecular Descriptors of Certain Otis Interconnection Networks
(Universidad Catolica del Norte, 2020) Cancan, M.; Ahmad, I.; Ahmad, S.
Network theory as an important role in the field of electronic and electrical engineering, for example, in signal processing, networking, communication theory, etc. The branch of mathematics known as Graph theory found remarkable applications in this area of study. A topological index (TI) is a real number attached with graph networks and correlates the chemical networks with many physical and chemical properties and chemical reactivity. The Optical Transpose Interconnection System (OTIS) network has received considerable attention in recent years and has a special place among real world architectures for parallel and distributed systems. In this report, we compute redefined first, second and third Zagreb indices of OTIS swapped and OTIS biswapped networks. We also compute some Zagreb polynomials of understudy Networks. © 2020 Murat Cancan, Iftikhar Ahmad, and Sarfarz Ahmad.
On Exploring the Topological Aspects of the Chemical Structure of the Nanotube Hac5c7
(Utilitas Mathematica Publishing Inc., 2024) Zakir, M.S.; Naseer, M.K.; Farahani, M.R.; Ahmad, I.; Kanwal, Z.; Alaeiyan, M.; Cancan, M.
Graph theory has experienced notable growth due to its foundational role in applied mathematics and computer science, influencing fields like combinatorial optimization, biochemistry, physics, electrical engineering (particularly in communication networks and coding theory), and operational research (with scheduling applications). This paper focuses on computing topological properties, especially in molecular structures, with a specific emphasis on the nanotube HAC5C7[w, t]. © 2024 Utilitas Mathematica Publishing Inc..

Study of Topology of Block Shift Networks Via Topological Indices
(Universidad Catolica del Norte, 2020) Cancan, M.; Ahmad, I.; Ahmad, S.
Topological indices(TIs) are important numerical number associate with the molecular graph of a chemical structure/compound because due to these parameters, one can guess almost all properties of concerned structure/compound with our performing experiments. In recent years, huge amount work has been done for calculating degreedependent indices for different structures/compouds. In order to compute TIs, one need to do many calculations. Our aim of this paper is to present a simple method to compute degree-dependent TIs. We computed M-polynomials for Block Shift Networks and with the help of this simple algebraic polynomials, we recovered nine important TIs for Block Shift Networks. Our work is important for chemists, physicians and pharmaceutical industry. © 2020 Murat Cancan, Iftikhar Ahmad, and Sarfarz Ahmad.
