Rosenthal has called this type of argument "Ramsey's Theorem for Analysts", see my answer here, so it could as well be called a "Ramsey trick". | |

| Apr 26, 2014 at 2:04 | comment | added | KConrad | I wouldn't be surprised if it's only the idea of diagonalization that is due to Cantor (in his proof of uncountability of $[0,1]$) and its particular manifestation for iterated subsequences was due to someone else later. | |
