I have a friend, he is working as PhD student in Applied Mathematics and he try to reach only on journal paper during his PhD program. But he said it is quite difficult some points. Is he not enough the ability in studying?

Otherwise, it seems you can write one journal paper per week, can’t you?

How could you do that? Tell us the secrete?

Thanks a lot in advance!

Dear Joel Kisten,

Please leave me your email so that I can email you directly. You can post your email together with your comment. Fortunately, WordPress will not show your email within the post.

Thank you.

Hi Mr Ngo,

Unfortunately, I have used the last email for along time. My current email is joel.kisten02@…. I would like to keep in touch with you and we can exchange a bit a bout our work.

Thank you very much for your reply.

I am looking forward to receiving your reply.

Best regards,

With my experiences, those integrals are very important, not only for understanding some relevant courses in Analysis but also for writing a research paper (even an important one, published on a good journal).

Whenever you actually write a research paper, you will know how valuable those inequalities are.

I do believe Mr. Ngo is doing a very good job, which cannot easily be done by others. Let’s congratulate him, give him more inspiration!

Comment by ULF — November 12, 2009 @ 5:22

Certainly publishing on high-ranking journals is very important. This does not mean papers on lower-ranking journals are meaningless.

Everything must be step by step.

However what Mr. Ngo has obtained is huge, in compared with his highest tittle.

Comment by ULF — November 12, 2009 @ 5:26

Theo tôi nghĩ không phải chạy theo số bài báo mà nên theo chất lượng của bài báo. Có người chỉ đăng có 2-3 bài báo mà được thế giới công nhận là chuyên gia đầu ngành.

Comment by MATH — February 20, 2010 @ 23:55

Both, in my opinion.

You can invest your studies in two directions: long-term problems, and the rest.

You should not criticize a person who has many publications. You had better do it, if possible.

2-3 papers are enough to be at the top. It is possible. But in this world, there are just a few people like that. One must be careful to imagine to be another Bao Chau Ngo, who is an extraordinary case.

I do not know whom or what Mr. Ngo is. But his contributions should be appreciated.

Comment by ULF — February 21, 2010 @ 8:06

Số lượng bài báo của anh NQA chứng tỏ là anh ấy là người tích cực nghiên cứu, chuyện công khai CV ở nước ngoài là bình thường. Đáng buồn là nhiều người có học vị cao mà không nghiên cứu gì hoặc rất lười nghiên cứu. Các paper của anh NQA nói chung không phải là những bài có thể gọi là “gây được sự chú ý”, nhưng thế là đã khởi đầu khá tốt cho con đường khoa học của mình rồi. Không ai đi so sánh những người làm toán với nhau. Hi vọng một ngày nào đó có thể thấy anh ở Ann. Math. hay Proc. Amer. Math. Soc.,…

To compare with the guys in this link “http://www.flickr.com/photos/47624590@N04/”, Mr. Ngo is great.

Now research criteria are not clear in Vietnam. Therefore we should congratulate Mr. Ngo and encourage him to carry out more results.

Thank ULF for this helpful information. BTW, my joint work

Nonlinear Anal. 70 (2009), pp. 1536-1546is ranked 15 according to the list. That’s amazing :).Comment by Ngô Quốc Anh — March 1, 2010 @ 21:58

Yeah! I have checked your profile carefully before supporting you. I do not have much free time for thoughtless claims as other guys did.

Every comment should be based on trustworthy sources, not just from personal affairs.

I do hope you work harder and more determined. Then you can close innocent mouths.

To be honest, after Mr. Ngo defends his PhD thesis, and builds a more official homepage (not just a blog), I am willing to recommend him to Mathematical Reviewer, to be a reviewer, if he has interest in it. Please email me about this theme whenever it is possible, Mr. Ngo!

Mathematical Reviewer—-> Mathematical Reviews. Sorry.

As I told, journals’ ranking is somehow possibly used to estimate a mathematician’s profile. But it is not always correct.

In order to conclude if a guy’s is good or not, there are different criteria needed.

All in all, I do appreciate your efforts. But I do not agree when you felt very “confident” about

Nonlinear Anal.The impact factors of Bulletin of London… or Journal of London…. may be rather lower than Nonlinear Anal.’s; however, I am not sure if you can easily get one paper accepted by these journals after you possibly have 5 papers in Nonlinear Anal.As I advised you, your achievement is okay. But keeping silent and working harder and publishing papers in more prestigious journals should be considered.

Good luck!
