The problem of prey and predator is solved by the differential transformation method (DTM). Numerical comparisons with Adomian decomposition method (ADM) and power series method are presented.

In this study, we constructed and analysed a mathematical model of COVID-19 in order to comprehend the transmission dynamics disease. The reproduction number (RC) was calculated via next generation matrix method. We also used Lyaponuv method show global stability both disease free endemic equilibrium points. results showed that disease-free point is globally asymptotically stable if RC > 1. fur...
