The method of upper and lower solutions for initial value problem of Caputo fractional differential equations with variable moments of impulse. (English) Zbl 1362.34013

Summary: In this paper sufficient conditions for the existence of a solution for the initial value problem of Caputo fractional differential equations of order \(q\), \(0<q<1\), with variable moments of impulse using the method of upper and lower solutions are established under the weakened hypothesis of \(C^q\) continuity.
