一、To my understanding, the results proved by the authors are new and of interest.
The paper is well written and well organized and I recommend it for publication in ***.
I would like to make a suggestion before publication. As the proofs in the paper are very similar to the proofs
in the reference 15, I think the authors should include a commentary at the beginning of sections 3, 4 and 5,
just like they did at the beginning of section 2, saying that they mainly follow reference 15.
Finally, there are some misprints that should be corrected.
二、In general, the paper is clear and well-written. According to my knowledge, the
results seem to be new and I do not see any particular problem (unless there is some
with the technical aspects, which I did not check all calculations). I am pleased to
recommend it for publication in Nonlinear Analysis.
Here are just a few typos, misprints (probably there many others) and minor
comments that the authors should address before publication.

看起来挺好，但编辑两个月了不给意见，也不回信，这一般是什么情况？有救么？ 返回小木虫查看更多
