ulam’s stability of impulsive sequential coupled system of mixed order derivatives

This manuscript is devoted to establishing hyers–ulam stability for a class of non-linear impulsive coupled sequential fractional differential equations with multi point boundary conditions on a closed interval [0,t] with caputo fractional derivative having non-instantaneous impulses. sufficient conditions are introduced that guarantee the existence of a unique solution to the proposed problem. furthermore, hyers–ulam stability of the proposed model is also presented and an example is provided to authenticate the theoretical results.
