On the separation of solutions to fractional differential equations of order $\alpha \in (1,2)$

Abstract

Given the Caputo-type fractional differential equation $D^{\alpha }y(t)=f(t,y(t))$ with $\alpha \in (1,2)$, we consider two distinct solutions $y_1,y_2\in C[0,T]$ to this equation subject to different sets of initial conditions. In this framework, we discuss nontrivial upper and lower bounds for the difference $|y_1(t)-y_2(t)|$ for $t\in [0,T]$. The main emphasis is on describing how such bounds are related to the differences of the associated initial values.
