Results on Certain Biopolymers Using M-Polynomial and NM-Polynomial of Topological Indices. [PDF]
Comput Math Methods Med, 2023 Topological indices are numerical descriptors that aid in the prediction of chemical molecules’ physiochemical properties and biological actions. It is often helpful to forecast numerous physiochemical attributes and biological actions of molecules in chemometrics, bioinformatics, and biomedicine.

Power Graphs of Finite Groups Determined by Hosoya Properties. [PDF]
Entropy (Basel), 2022 Suppose G is a finite group. The power graph represented by P(G) of G is a graph, whose node set is G, and two different elements are adjacent if and only if one is an integral power of the other. The Hosoya polynomial contains much information regarding

A method for computing the edge-Hosoya polynomial with application to phenylenes [PDF]
, 2023 The edge-Hosoya polynomial of a graph is the edge version of the famous Hosoya polynomial. Therefore, the edge-Hosoya polynomial counts the number of (unordered) pairs of edges at distance $k ge 0$ in a given graph. It is well known that this polynomial

A New Graphical Representation of the Old Algebraic Structure
Journal of Mathematics, Volume 2023, Issue 1, 2023., 2023 The most recent advancements in algebra and graph theory enable us to ask a straightforward question: what practical use does this graph connected with a mathematical system have in the real world? With the use of algebraic approaches, we may now tackle a wide range of graph theory‐related problems.
