Hdr degree bassed indices and mhr-polynomial for the treatment of covid-19

In this research work, We introduce topological indices, namely as an HDR version of Modified Zagreb topological index (HDRM*), HDR version of Modified forgotten topological index (HDRF*), and HDR version of hyper Zagreb index (HDRHM*). Then the relatively study depends on the structure-property regression analysis to test and compute the chemical applicability of these indices to predict the physicochemical properties of octane isomers. Also, we show these HDR indices have well degeneracy properties compared to other degree-based topological indices. Also, We defined and computed the Mhr-polynomial of the newly indices and applied it on COVID-19 treatments. Also, we discussed some mathematical properties of HDR indices. © 2021 by the authors.

Domination, gamma-Domination Topological Indices and phi(P)-Polynomial of Some Chemical Structures Applied for the Treatment of COVID-19 Patients

In medical science, pharmacology, chemical, biological, pharmaceutical properties of molecular structure are essential for drug preparation and design. These properties can be studied by using topological indices calculation. In this research work, we establish the topological properties of some chemical structures that have been applied for the treatment of COVID-19 patients by using the domination of topological indices and gamma-domination indices. We determine the phi(P) - polynomial for the antiviral chemical structures. The results obtained can help study the chemical properties of chemical structures that have been applied for the treatment of COVID-19 patients.
