However, personally (and this is a subjective matter) I will find it harder to explain all details of this argument to students than, say, Petrov's argument here. In any case, I'm drifting off the scope of this problem. My survey is aimed at advanced students and researchers, not undergrads. (But ones that never learned undergrad descriptive set theory, or didn't see various constructions of Cantor's set / CB Thm, etc.) | |
