As I’d said about a month ago, I’m hoping to panel topics for this year’s A-To-Z in a more piecemeal manner. Mostly this is so I don’t lose track of requests. I’m hoping not to go more than about three weeks between when a topic gets brought up and when I actually commit words to page.

But please, if you have any mathematical topics with a name that starts G through M, let me know! I generally take topics on a first-come, first-serve basis for each letter. But I reserve the right to use a not-first-pick choice if I realize the topic’s enchanted me. Also to use a synonym or an alternate phrasing if both topics for a particular letter interest me. Also when you do make a request, please feel free to mention your blog, Twitter feed, Mathstodon account, or any other project of yours that readers might find interesting. I’m happy to throw in a mention as I get to the word of the day.

So! I’m open for nominations. Here are the words I’ve used in past A to Z sequences, for reference. I probably don’t want to revisit them, but if someone’s interested, I’ll at least think over whether I have new opinions about them. Thank you.

And there we go! … To avoid confusion I’ll mark off here when I have taken a letter.

And all the Fall 2018 Mathematics A-To-Z should appear at this link, along with some extra stuff like these topic-request pages and such.

L is for Limit ?

Oh, that’s a great one! Thank you.

Should G be something Gross or Golden? ha ha

J Jokes only a mathematician could love?

I quite like all these suggestions, actually; they’re a bit outside the box and those are often the most fun ones. There should at least be a couple hundred words to write about the kind of humor made for mathematicians.

How about “Group Action” for G, and “Manifold” for M?

LikeLike

Both good suggestions too! Manifold particularly. Thank you.

All great suggestions, thank you. Manifold particularly seems to be on people’s minds this season!
