Question: Where can one find information on which areas of mathematics are represented at which of the more than 20 universities in the Democratic People's Republic of Korea (DPRK), and on which mathematicians are working there?

The DPRK is a country with a population of about 25 million people, and it is industrialised to a degree which has permitted it to successfully construct nuclear weapons and ICBM's. So one would expect that there are a decent number of mathematicians working at its universities.

However as the country operates an intranet of its own, not much from there is visible from the open internet. -- So in particular Google will not help much further here. Also, most results by researchers from the DPRK are published only in national journals, and mathematicians from the country cannot be found in the Mathematics Genealogy Database. On the other hand, people in the DPRK who need the internet for their work do have access, but with some sites blocked and email possibly monitored.

Edit: The possibly most interesting source available on the open internet I found so far is NKScholar. -- But firstly articles posted on that site are paywallet with prices in local currency, and secondly the site is Korean-language only -- so I can't tell how much one can really find there. Maybe someone else can tell more.

Two mathematicians from North Korea I know are Kim, Jinhyon and Ju, Hyonhui. I like their paper:

Hausdorff dimension of the sets of Li-Yorke pairs for some chaotic dynamical systems including A -coupled expanding systems. (English) Zbl 1390.37028 Chaos Solitons Fractals 109, 246-251 (2018).

Interesting! -- By the way -- do you know which of the articles listed in zbMATH at are actually by Kim, Jinhyon (only the one you mentioned is published under the full name, and 35 others on the list are authored by some Kim, J.).

@Jörg Neunhäuserer 2019-01-12 14:36:06

Sorry but I do not know this for sure.

Unrelatedly, there’s quite an interesting story about that journal and its former editor, Mohamed El Naschie. This is now nearly a decade ago and I don’t want to assume the new editors behave like the old ones. But interesting to say the least.

@Stefan Kohl 2019-01-12 17:03:04

@pupshaw: That is indeed interesting. -- Do you think one can find a significant amount of serious research in that journal anyway?

@Stefan Kohl 2019-01-12 17:14:22

@JörgNeunhäuserer: Since the paper you cite is far from my area of expertise, I cannot tell anything about its correctness or merits. -- Given what pupshaw said -- can you confirm it is a reasonable paper, or is it possible that it is not without reason that the authors have chosen a journal with that reputation?

About CS&F there is an analysis from 2010:

@Jörg Neunhäuserer 2019-01-12 21:32:21

@StefanKohl In my opinion it is a good paper! The authors generalize my results in Li-Yorke pairs of full Hausdorff dimension for some chaotic dynamical systems. (English) Zbl 1224.37011 Math. Bohem. 135, No. 3, 279-289 (2010).

Here are some articles on cryptography. (I do not claim the veracity of them, as there is a lot of misinformation.)

@Stefan Kohl 2019-01-11 14:37:57

Yes, this set of eight papers posted in 2005 is one of the few poor sources one finds with Google.

@EFinat-S 2019-01-11 16:08:25

I would bet that, going "deeper" in the web, one could find more.

@EFinat-S 2019-01-11 16:53:13

Google chrome translates webpages without installing any plugin. It worked for me for your link. Looking at the titles one notes that there's a lot of applied math.

@Stefan Kohl 2019-01-11 17:04:01

Yes, of course. -- This gives some headlines -- but no abstracts, author's affiliations or contact data, let alone full texts of articles.

@Stefan Kohl 2019-01-11 17:18:58

Besides -- does the search function work for you in a useful way via the translator?

@EFinat-S 2019-01-11 21:07:25

No, it does not work for me with the translator.

@Ofir Gorodetsky 2019-01-11 23:27:24

You can find in Math Reviews papers with authors affiliated with Kim Il-sung University, e.g. MR3225383, MR3232454 (in finite fields) MR3353738, MR3255419 (in differential geometry). Moreover, Math Reviews has institution information for Kim Il Sung University, see… .

@EFinat-S 2019-01-12 00:27:07

Dear Stefan. Your e-mail is the one appearing in your webpage?

@Stefan Kohl 2019-01-12 10:21:25

@EFinat-S Yes, it is.
