Notes on the Various Lists

There are three lists at present. One lists ring theorists by country and then University, one lists them alphabetically, and one is a much shorter list of web pages I found particulary helpful or interesting. There is also a page with other lists and other web pages for finding mathematicians. The various lists are certainly not complete, and they are perhaps also over-full, since who should be classified as a ring theorist is a non-trivial question.
Any additions (or deletions?), corrections, or comments should be addressed to Allen Bell at

Below you can find general information, some information on the compilation of the lists (and who's listed), and notes on names, special characters, and searching the lists. If you've never used these lists, I suggest you look at the the notes on names and searching.

General Information

As you would expect, links -- when available -- work by selecting an indivdual's or department's name, an e-mail address, or the words "MathSciNet Entry".

I tested the home page URLs during the summer of 1999 (and I've tested some of them at various times since then), but I did not test the e-mail addresses. I often list multiple e-mail addresses, obtained from different sources. Thus the e-mail addresses are much less reliable. Change is common and rapid on the Web, so the addresses or web page URLs may not work when you try them. I also find that some web pages are frequently unavailable even though the URL is correct. It is possible that a web page or e-mail address is correct, but that it is not the primary address, in which case e-mail may go unread and the web page may not be updated. If you know that this is the case with any address or web page on the lists, please let me know.

In addition to possible errors, there is no guarantee that people read their e-mail. Many home pages are very superficial and don't contain a lot of information. Many of them were probably not prepared by the individual and may never be updated.

The links to MathSciNet were working in Summer, 1999, but it is possible MathSciNet will change its structure and the links will cease to function. (This happened once before.) You can only access the MathSciNet links if the computer you are using is connected to the internet through a domain that subscribes to MathSciNet or you have an individual subscription.
The MathSciNet links are to the AMS server in the eastern US. I don't know how well this works in other parts of the world. If these lists ever become stable enough to mirror, it would probably be advisable to point the links to the closest MathSciNet mirror site. (This shouldn't be too hard -- I think. Talk to me if you're interested.)

The pages are fairly long and may take some time to load. If you have a problem using the lists, make sure the page is fully loaded and try again.

Compilation and who's listed

The lists are meant to include individuals who are active researchers in or have made signigicant contributions to the theory of non-commutative, associative rings. I wanted the lists to be substantial but not overly large. These desires introduced a subjective element. For example, are quantum groups and Lie theory ring theory? (My answer: generally yes if rings are involved in a significant way and the papers are classified under MR section 16 a lot of the time.) What about near rings and semirings? (I omitted these.) What about K-Theory and homological algebra? (I was pretty inconsistent about this.) What does active or significant mean? (Very subjective: There's no doubt that I was more likely to include people I knew.) I hope I've made reasonable decisions, but I'm certainly willing to consider other opinions. I cannot promise when I'll get around to further changes, but please do send me comments and corrections.

I compiled the lists starting with ring theorists I knew, then searching math department web pages, and finally using MathSciNet. So far external input has been welcome but fairly limited. However, I would like to thank Dinesh Khurana for helpful information on a number of ring theorists. I may send a mailing out at some point to test the e-mail addresses. In the beginning I used Lynx and Netscape; now I also use Internet Explorer and don't use Lynx much. I'm sure the pages could be better tested. I guess that will be the users' job.

Names, special characters, and searching the lists

If you wish to find an individual, you can either browse the alphabetical list to the last name or browse the "by location" list to the individual's University, or you can search for the name. I don't provide any search function, but your browser (i.e., Netscape, Internet Explorer, Lynx, Safari, Firefox, etc.) probably does: something like "Find on this page". You should read the notes below on how names are listed. (Watch out for accented characters .)
A few individuals are listed at more than one institution, so the first occurrence of the name you find will sometimes not be the best.
Note: The web pages containing the lists are fairly long and may take some time to load. If you search for a name shortly after opening the page, your search may fail because the part of the page containing the name has not yet loaded. In the same way, if you select a letter at the top of the page and your broswer does not jump to that part of the page, the page may not be fully loaded. If you have a problem, make sure the web page is fully loaded and try again.

If you're browsing the lists, you may find that I have made some odd decisions about alphabetizing, so Universities, names, etc., may not appear in exactly the order you expect.

Names of individuals occur in at least two formats. The first occurrence is the name as listed in the MathSciNet (Math Reviews) author database, without any accents or non-English characters (plain, old-fashioned ASCII), as in
Bell, Allen D. or Capablanca, Jose Raoul.
Note: I've tried to provide alternatives when there is the possibility of confusion. For example, Müller will be listed once as Muller and once as Mueller. For Chinese names, MathSciNet tends to prefer a form like Sun, Yat Sen while it appears to me that many people prefer the form Sun, Yatsen so I have tried to use both. (Sun, Yat-Sen is also common, but I have only used this form when I saw it used elsewhere.)

The name is then listed in what I think is the normal form, with non-English characters produced as best I can in HTML, as in
Allen D. Bell or José Raoul Capablanca. This last name is actually coded in the file as José Raoul Capablanca, so searching the page for Jose Raoul Capablanca will yield no matches. The point is that you probably cannot use non-English or accented (non-ASCII) characters in a search.
This last rule is broken sometimes in the current revision, because character sets with accented characters have become common and I sometimes copy and paste, so you might see Josť Raoul Capablanca with the ť a single character.

If you use certain browser/computer combinations, accented characters may be displayed incorrectly. Here's an example to test your system -- the letter e with two types of accent: è é

I have also tried to write names of Universities/Departments in something like their native language and in an anglicized form, although I wasn't consistent about this. I hope the many mistakes I have made will provide some amusement.
