On a related note, I'm fond of this Mathoverflow answer, "Which math paper maximizes the ratio (importance)/(length)?"[1] Highlights include: 1. A one-sentence proof published in American Mathematical Monthly that costs $19 to download on JSTOR, 2. The 8-page paper that introduced ζ (zeta) notation, two proofs of the ζ(s) L-function, several new methods in analytic and number theory, and (most famously) the Riemann Hypothesis, 3. Lebesque's paper introducing modern measure theory, 4. Elkies' paper proving the (titular) existence of infinitely many supersingular primes for every elliptic curve defined on the rationals. It seems it was a bit easier to publish short, dense material in the 20th century :) _________________________________ 1. https://mathoverflow.net/questions/7330/which-math-paper-maximizes-the-ratio-importance-length https://mathoverflow.net/questions/7330/which-math-paper-max...
