Ulam-Hyers-Rassias Stability of Nonlinear Differential Equations with Riemann-Liouville Fractional Derivative

Fractional derivatives are used to model the transmission of many real world problems like COVID-19. It is always hard find analytical solutions for such models. Thus, approximate interest in interesting applications. Stability theory introduces using some conditions. This article devoted investigation stability nonlinear differential equations with Riemann-Liouville fractional derivative. We employed a version Banach fixed point study sense Ulam-Hyers-Rassias (UHR). In end, we provide couple examples illustrate our results. this way, extend several earlier outcomes.
