Abstract:

This paper discusses the fractional evolution equations with piecewise Caputo derivative and periodic impulses. The existence and uniqueness of periodic mild solutions for the associated linear evolution equation with periodic impulses is established. With the aid of the expression of the solution operator for the linear impulsive periodic problem, some new existence results of periodic mild solutions for semilinear impulsive periodic problems are showed by means of the operator semigroup theory and fixed point theorems.

Key words: Impulsive fractional evolution equations, Periodic impulses, Periodic mild solutions, Existence, Compact semigroup
