Impulsive Multiorders Riemann-Liouville Fractional Differential Equations
Discrete Dynamics in Nature and Society, 2015 Impulsive multiorders fractional differential equations are studied. Existence and uniqueness results are obtained for first- and second-order impulsive initial value problems by using Banach’s fixed point theorem in an appropriate weighted space ...
