Keywordsboundary value problem Caputo type fractional derivative existence and uniqueness fixed point theorem impulsive integro-differential equation nonlocal condition
The topic of fractional differential equations has received a great deal of attention from many scientists and researchers during the past decades; see, for instance, [1–7]. This is mostly due to the fact that fractional calculus provides an efficient and excellent instrument to describe many practical dynamical phenomena which arise in engineering and science such as physics, chemistry, biology, economy, viscoelasticity, electrochemistry, electromagnetic, control, porous media; see [8–13]. Moreover, many researchers study the existence of solutions for fractional differential equations; see [14–16] and the references therein.
In particular, several authors have considered a nonlocal Cauchy problem for abstract evolution differential equations having fractional order. Indeed, the nonlocal Cauchy problem for abstract evolution differential equations was studied by Byszewski [17, 18] initially. Afterwards, many authors [19–21] discussed the problem for different kinds of nonlinear differential equations and integrodifferential equations including functional differential equations in Banach spaces. Balachandran et al. [22, 23] established the existence of solutions of quasilinear integrodifferential equations with nonlocal conditions. N’Guérékata  and Balachandran and Park  researched the existence of solutions of fractional abstract differential equations with a nonlocal initial condition. Ahmad  obtained some existence results for boundary value problems of fractional semilinear evolution equations. Recently, Balachandran and Trujillo  have investigated the nonlocal Cauchy problem for nonlinear fractional integrodifferential equations in Banach spaces.
On the other hand, the theory of impulsive differential equations for integer order has emerged in mathematical modeling of phenomena and practical situations in both physical and social sciences in recent years. One can see a significant development in impulsive theory. We refer the readers to [28–31] for the general theory and applications of impulsive differential equations. Besides, some researchers (see [32–35] and the references therein) have addressed the theory of boundary value problems for impulsive fractional differential equations.

Note that in this work, to the best of our knowledge, it is the first time that a general boundary value problem for impulsive semilinear evolution integrodifferential equations of fractional order with nonlocal conditions has been considered.
The rest of this paper is organized as follows. In Section 2, we present some notations and preliminary results about fractional calculus and differential equations to be used in the following sections. In Section 3, we discuss some existence and uniqueness results for solutions of BVP (1.1). Namely, the first result is based on Schauder’s fixed point theorem and the second one is based on Banach’s fixed point theorem. Finally, we shall give an illustrative example for our results.

Substituting the value of in (2.5) and (2.6), we obtain Eq. 2.3.
Conversely, if we assume that u satisfies the impulsive fractional integral equation (2.3), then by direct computation, we can easily see that the solution given by (2.3) satisfies (2.4). Thus, the proof of Lemma 3 is complete. □
3 Main results
Clearly, the fixed points of the operator T are the solutions of problem (1.1). To begin with, we need the following assumptions to prove the existence and uniqueness of a solution of the integral equation (2.3) which satisfies BVP (1.1):
(A1) is a continuous bounded linear operator and there exists a constant such that for all ;
(A2) The function is continuous and there exists a constant such that ;
(A3) are continuous and there exist constants and such that for each and ;
(A4) There exist constants and are continuous functions such that , ;
, and ;
for all ;
(A7) There exist constants , such that , for each and ;
(A8) There exist constants such that , .
The following are the main results of this paper. Our first result relies on Schauder’s fixed point theorem which gives an existence result for solutions of BVP (1.1).
Theorem 1 Assume that the assumptions (A1)-(A4) hold. Then BVP (1.1) has at least one solution on J.
Proof In order to show the existence of a solution of BVP (1.1), we need to transform BVP (1.1) to a fixed point problem by using the operator T in (3.1). Now, we shall use Schauder’s fixed point theorem to prove T has a fixed point which is then a solution of BVP (1.1). First, let us define for any . Then it is clear that the set is a closed, bounded and convex. The proof will be given in several steps.
Step 1: T is continuous.
Since A is a continuous operator and f, g, I, are continuous functions, we have as .
Step 2: T maps bounded sets into bounded sets.
Then it follows that .
Step 3: T maps bounded sets into equicontinuous sets.
Hence, is equicontinuous on all the subintervals , . Then we can deduce that is completely continuous as a result of the Arzela-Ascoli theorem together with Steps 1 to 3.
As a consequence of Schauder’s fixed point theorem, we conclude that T has a fixed point. That is, BVP (1.1) has at least one solution. The proof is complete. □
Our second result is about the uniqueness of the solution of BVP (1.1). And it depends on Banach’s fixed point theorem.
Therefore, by (3.2), the operator T is a contraction. As a consequence of Banach’s fixed point theorem, we deduce that T has a fixed point which is a unique solution of BVP (1.1). □
where , , and , are given positive constants with and .
Therefore, due to the fact that all the assumptions of Theorem 2 hold, BVP (3.3) has a unique solution. Besides, one can easily check the result of Theorem (1) for BVP (3.3).
In the literature, the authors consider impulsive fractional semilinear evolution integro-differential equations of order in different aspects as mentioned above. Besides, either impulsive fractional semilinear equations of order or impulsive fractional integro-differential equations of order are studied by different authors (see, for instance, [44, 45]). But, to the best of our knowledge, no study considering both cases has been carried out. Thus, in this article, we consider a general boundary value problem for impulsive fractional semilinear evolution integro-differential equations of order with nonlocal conditions. Therefore, the present results are new and complementary to previously known literature.
