I’m looking for Y and Z topics for the All 2020 A-to-Z


I decided to let the V essay slide to Wednesday. This will make the end of the 2020 A-to-Z run a week later than I originally imagined, but that’s all right. It’ll all end in 2020 unless there’s another unexpected delay.

I have gotten several good suggestions for the letters W and X, but I’m still open to more, preferably for X. And I would like any thoughts anyone would like to share for the last letters of the alphabet. If you have an idea for a mathematical term starting with either letter, please let me know in comments. Also please let me know about any blogs or other projects you have, so that I can give them my modest boost with the essay. I’m open to revisiting topics I’ve already discussed, if I can think of something new to say or if I’ve forgotten I wrote them about them already.

  1. I like the idea of “zero divisor” for ‘Z’. I’m not sure if it would lead to a good article or not, but I remember feeling intense curiousity, once upon a time, about the idea of things that aren’t zero multiplying together to make zero.
    Zorn’s Lemma could be a fruitful topic, too, I suppose.
