Non-Instantaneous Impulsive Fractional Differential Equations with State Dependent Delay and Practical Stability

Nonlinear delay Caputo fractional differential equations with non-instantaneous impulses are studied and we consider the general case of delay, depending on both time state variable. The when lower limit derivative is fixed at initial time, changed end each interval action impulse studied. Practical stability properties, based modified Razumikhin method investigated. Several examples given in this paper to illustrate results.
