I Ask For The First Topics For My Fall 2019 Mathematics A-To-Z

And a good late August to all my readers. I’m as ready as can be for my Fall 2019 Mathematics A-To-Z. For this I hope to explore one word or concept for each letter in the alphabet, one essay for each. I’m trying, as I did last year, to publish just two essays per week. I like to think this will keep my writing load from being too much. I’m fooling only myself.

For topics, though, I like to ask readers for suggestions. And I’ll be asking just for parts of the alphabet at a time. I’ve found this makes it easier for me to track suggestions. It also makes it easier for me to think about which subjects I feel I can write the most interesting essay about. This is in case I get more than one nomination for a particular letter. That’s hardly guaranteed, but I do like thinking this might happen.

If you do leave a suggestion, please also mention whether you host your own blog or YouTube channel or Twitter or Mathstodon account. Anything that you’d like people to know about.

I’ve done five of these A To Z sequences before, from 2015 through to last year. I won’t necessarily refuse to re-explore something I’ve already written up. There are certainly ones I could improve, given another chance. But I’d probably look to write about a fresh topic.

I hope to start the first week of September, mostly so that I end by (United States) Thanksgiving. The letters that I would like to finish by September are the first eight, A through H. Covered in past years from this have been:

A.

Ansatz (Summer 2015)
Axiom (Leap Day 2016)
Algebra (End 2016)
Arithmetic (Summer 2017)
Asymptote (Fall 2018)

E.

Error (Summer 2015)
Energy (Leap Day 2016)
Ergodic (End 2016)
Elliptic Curves (Summer 2017)
e (Fall 2018)

F.

Fallacy (Summer 2015)
Fractions (continued) (Leap Day 2016)
Fredholm Alternative (End 2016)
Functor (Summer 2017)
Fermat’s Last Theorem (Fall 2018)

G.

Graph (Summer 2015)
Grammar (Leap Day 2016)
General Covariance (End 2016)
Gaussian Primes (Summer 2017)
Group Action (Fall 2018)

H.

Hypersphere (Summer 2015)
Homomorphism (Leap Day 2016)
Hat (End 2016)
Height Function (elliptic curves) (Summer 2017)
Hyperbolic Half-Plane (Fall 2018)

Thank you for any thoughts you have. Please ask if there are any questions. And I intend for this to be open to topics in any field of mathematics, including the ones I don’t really know. Writing about something I’m just learning about is terrifying and fun. It’s a large part of why I do these things every year, and also why I don’t do them more than once a year.
