The oldest articles are a couple from 1997, most are from the naughts. This is interesting - not sure how to explain it, but perhaps it’s about research groups focusing on specific topics and being very prolific in their work, leaving other topics on the sidelines and silencing them out (in the above citation terms) by quantity too?
Could there be a cite-latest-article-on-topic practice as opposed to citing back to the origins?
There’s a significant gap between the first (941) and second (382) and consecutive most cited papers.
Top of the list (with aforementioned 941 citations): a manual for a software package for symbolic manipulation with no “new math result” as far as I can tell. So there, write a (clearly very useful) SW package and you get to the top of the list of citations in maths!
The subtitle of the list says ‘The 100 most highly cited …’ but there’s only 74 on the list :) #pedantic
Finally, I haven’t heard about or read any of them and struggle to even understand the titles :) I expected papers on things like optimisation (lp, qp, convex in general …) or linear and matrix algebra (SVD or eigenvalue stuff) or some number theory related to cryptography or data communication (redundancy, …) - but clearly I’m out of touch and too much in engineering by now.
