44 influential journal articles

Same idea as 44 Great Books, but for journal articles. Influence is measured by the number of citations on MathSciNet, and as such is subject to chronological and geographical bias. Italic indicates I took a look at the paper, whether or not I got anything out of it.

The earliest paper on the list was published in 1938 (see Geometry), the latest in 2000 (see K-theory). Half were published in 1977 or later.

Notes

  • (1) In combinatorics, the Erdős-Rényi paper is slightly behind Emergence of scaling in random networks by Barabási and Albert (1999). I disqualified the latter for being published in Science.
  • (2) The 1981 paper by Hutchinson on fractals was classified under Calculus of variations, and would be the most cited in that category. However, this is an artifact of MSC which did not have a classification for Fractals until 1991. Now they are under Measure and Integration (28A80).
  • (2) If I did not move Hutchinson’s paper to Measure and Integration, the winner there would be A relation between pointwise convergence of functions and convergence of functionals by Brézis and Lieb (1983). Notably, this is a 5-page paper in the Proceedings of the AMS.

Finally, some trivia based on the combined lists of 44 books and 44 papers.

  • Pierre-Louis Lions is the only person with three entries: most cited papers in ODE, PDE, and Calculus of Variations
  • Juha Heinonen, Walter Rudin, and Stephen Smale have entries in two different MSC areas:
    • Heinonen: most cited book in Potential Theory and most cited paper in One Complex Variable (another artifact of MSC: analysis on metric spaces is under MSC 30)
    • Rudin: most cited books in General and in Several Complex Variables
    • Smale: most cited papers in History/Biography and in Manifolds/Cell Complexes.
  • Victor Kac and Eliah Stein occupy both top spots (book and paper) in the same area:
    • Kac: Nonassociative Groups and Algebras
    • Stein: Harmonic Analysis on Euclidean Spaces

No Disrespect Meant (on MathSciNet institution codes)

According to The Free Dictionary, the title is one of the meanings of the acronym NDM. Recently MathSciNet began to append the suffix NDM to the institution codes which it uses to indicate an author’s affiliation. So, instead of

1-SRCS: “This author is at Syracuse.”

you sometimes see

1-SRCS-NDM: “This author is at Syracuse. No disrespect meant.”

This change appears to be very recent (all papers with the -NDM suffix that I’ve seen were indexed in 2012) and its likely goal is to keep the unsuffixed codes, such as 1-SRCS, for the output of math departments only. MathSciNet long used the suffix -P for physics, as in 1-SRCS-P. But if physicists did not specifically mention their departmental affiliation, they could sneak in.

But no more! From now on, the lack of departmental affiliation marks you with the suffix -NDM, which I guess expresses the frustration of MathSciNet staff: “No Department, #*&$%*^!”. It is not to be confused with the code 1-NDM, which stands for Notre Dame math department. When the Notre Dame code acquires this suffix, is becomes 1-NDM-NDM.

Moral: to be admitted into the unsuffixed club, you must show your credentials, i.e., put your department in the author address field. Your name will not be enough, even if it is Terence Tao or Richard P. Stanley. No disrespect meant.

Apropos of et al

I have 111 MathSciNet reviews posted, and there are three more articles on my desk that I should be reviewing instead of blogging. Even though I think of canceling my AMS membership, I don’t mind helping the society pay their bills (MathSciNet brings about 37% of the AMS revenue, according to their 2010-11 report.)

Sure, reviews need to be edited, especially when written by non-native English speakers like myself. Still, I’m unhappy with the edited version of my recent review:

This was the approach taken in the foundational paper by J. Heinonen et al. [J. Anal. Math. 85 (2001), 87-139]

The paper was written by J. Heinonen, P. Koskela, N. Shanmugalingam, and J. T. Tyson. Yes, it’s four names. Yes, the 14-letter name is not easy to pronounce without practice. But does the saving of 45 bytes justify omitting the names of people who spent many months, if not years, working on the paper? Absolutely not. The tradition of using “et al” for papers with more than 3 authors belongs to the age of typewriters.

P.S. I don’t think MathSciNet editors read my blog, so I emailed them.

P.P.S. The names are now restored. In the future I’ll be sure to add in “comments to the editor” that names should not be replaced by et al.
