Existence of Solutions for Anti-Periodic Fractional Differential Inclusions Involving ψ-Riesz-Caputo Fractional Derivative
Round 1
Reviewer 1 Report
The paper continues a series of works on proving the existence of solutions of fractional differential equations and inclusions with anti-periodical boundary conditions moving forward from Riesz-Caputo and psi-Caputo derivatives to the fractional inclusions with newly introduced psi-Riesz-Caputo derivative.
The main novelty of the paper is a presentation and usage of a new definition of fractional derivative, namely the psi-Riesz-Caputo derivative.
The conditions of the existence of solutions are obtained using fixed point theorems within the general approach used previously for other similar problems, particularly, in the works cited in the reviewed paper.
The paper is well written and presents new valuable results. However, Introduction structure can be improved rearranging paragraphs to make it more logical. At least, from my point of view, a paragraph with general considerations about fractional calculus (starting from the line 31) will look more appropriate at the beginning of the Introduction.
Author Response
We rearranged our introduction as your suggestions in order to let it seems more logic. Please see the attachedment.

Reviewer 2 Report
Please expand the abstract section. In line 12 you wrote: "By means of some standard fixed point theorems..." What theorems did you mean?
In the introduction section, provide more background about the problem you are considering.
Please expand the application section. Add more examples and compare with others.
Please add the conclusion section.
Also, I found the following errors:
Formulas in definition 1 are Caputo fractional derivate but not integral;
In definition 3 there is an error in the word «fractional».
Author Response
(1) We add the tools of this paper in abstract.
(2) We add line 49-55 as the background about the problem in the introduction.
(3) We expand our applications section.
(4) We add the conclusion section.
(5) We make it correct in Definition I ( derivative)and Definition 3 ( fractional)

Reviewer 4 Report
1. On page 3, clarify what kind of fractional operators could be obtained from Def.4.
2. Include some references for the definitions presented in the paper.
3. When mention a function, write f and not f(x). E.g. on Lemma 6, write u\in...and not u(t)\in...
4. Several works on psi-FDE are not mentioned in the paper e.g.
Fractional differential equations with a Caputo derivative with respect to a kernel function and their applications. Math. Meth. Appl. Sci. (41), 336-352 (2018)
or
On systems of fractional differential equations with the psi-Caputo derivative and their applications. Math Meth Appl Sci. (in press)
Please cite these and other references on similar subject.

On page 3, clarify what kind of fractional operators could be obtained from Def.4.
We add remark 1 as the clarification, see new lines 108-109.
2. Include some references for the definitions presented in the paper.
We list all the references for the definitions, except the one we defined ourselves.
3. When mention a function, write f and not f(x). E.g. on Lemma 6, write u\in...and not u(t)\in...
We make a change, please see new line 185
