Deletion of Mikhail Katz

Comment: on basis of pass of rof#C1. Looking back on the past history of these academic AfD debates I find that many hundreds of publications are expected to pass rof#C1. Subjects with h index|h indices of less than 10 are usually found to be not notable, those with greater than 15 are usually found to be notable. The intermediate range often leads to much discussion, as in this case. However, it had several times been suggested that the citation rates in mathematics are generally lower than in other subject (I wish we had reliable data on this) and so I think that this BLP qualifies for a pass of the above average professor test

Comment: I'm not convinced of a pass of  on the basis of absolute citation counts — yes, it's a lower citation field, but he's had plenty of time in his career to accumulate citations. I would normally find Ruud's argument about incoming links more convincing — perhaps surprisingly since it isn't one of the  criteria, but I think that high connectivity is important to the encyclopedia. On the other hand, in order to test where those incoming links were coming from, I chose arbitrarily one of them, Hurwitz quaternion order, and found that the article had been created and edited heavily by Katz, that he was the one who added the citation to his own paper to the article, and that the citation is nowhere used within the text of the article. I don't view adding relevant self-citations to articles as a bad thing (I've done it enough times myself) but their relevance needs to be justified (which it wasn't in this case) and it makes me uncomfortable to then use the existence of such links as a basis of keeping the biography. What eventually did tip me over from delete to keep was to look, not at the citation counts, but at who the top authors in systolic geometry are. It's a little difficult because the search results for "systolic" are dominated by heart research and distributed computing, but with the more mathematical keyword combinations I tried the consistent results were that Gromov was far and away the most heavily cited, but that many of the next most cited papers after his were by Katz. So it seems he really is a leader in this sub-area, and I think it's an important enough sub-area that being a leader in it should be enough
