## 2021 Abel Prize

I am overjoyed with the news of the *Abel prize* awarded to **László Lovász** and** Avi Wigderson**. You can now see three (!) Abel laureates discussing Combinatorics — follow the links in this blog post from 2019. See also Gil Kalai’s blog post for further links to lectures.

## My interview

Readers of this blog will remember my strong advocacy for taking interviews. In a surprising turn of events, Toufik Mansour interviewed me for the journal *Enumerative Combinatorics and Applications* (ECA). **Here is that interview**. Not sure if I am the right person to be interviewed, but if you want to see other Toufik’s interviews — **click here** (I mentioned some of them earlier). I am looking forward to read interviews of many more people in ECA and other journals.

**P.S.** The interview asks also about this blog, so it seems fitting to mention it here.

**Corrections:** (March 11, 2021) **1.** I misread “What three results do you consider the most influential in combinatorics during the last thirty years?” question as asking about *my own* three results that are specifically in combinatorics. Ugh, to the original question – none of *my* results would go on that list. **2.** In the pattern avoidance question, I misstated the last condition: I am asking for *e*^{c(Π)} to be non-algebraic. Sorry everyone for all the confusion!

## How to tell a good mathematical story

As I mentioned in my previous blog post, I was asked to contribute to to the **Early Career Collection** in the *Notices of the AMS*. The paper is not up on their website yet, but I already submitted the proofs. So if you can’t wait — the short article is **available here**. I admit that it takes a bit of a chutzpah to teach people how to write, so take it as you will.

Like my previous “*how to write*” article (see also my blog post), this article is mildly opinionated, but hopefully not overly so to remain useful. It is again aimed at a novice writer. There is a major difference between the way *fiction *is written vs. *math*, and I am trying to capture it somehow. To give you some flavor, here is a quote:

What kind of a story?Imagine a non-technical and non-detailed version of the abstract of your paper. It should be short, to the point, and straightforward enough to be atweet, yet interesting enough for one person towantto tell it, and for the listener curious enough to be asking for details. Sounds difficult if not impossible? You are probably thinking that way, because distilled products always lack flavor compared to the real thing. I hear you, but let me give you some examples.Take Aesop’s fable “

” written over 2500 years ago. The story would be “The Tortoise and the HareA creature born with a gift procrastinated one day, and was overtaken by a very diligent creature born with a severe handicap.” The names of these animals and the manner in which one lost to another are less relevant to the point, so the story is very dry. But there are enough hints to make some readers curious to look up the full story.Now take “

”, the original 1984 movie. The story here is (spoiler alert! ) “The TerminatorA man and a machine come from another world to fight in this world over the future of the other world; the man kills the machine but dies at the end.” If you are like me, you probably have many questions about the details, which are in many ways much more exciting than the dry story above. But you see my point – this story is a bit like an extended tag line, yet interesting enough to be discussed even if you know the ending.
