Why does my email automatically filter out my math listserv emails but let through "One last chance to transform the way education works" from some predatory publishing company? Also, do I care enough to actually set filters to make this right?

Very proud of my student, who made major technical contributions to this new paper on infinitary commutativity! arxiv.org/pdf/2001.09500…

It can get a bit technical if you're still getting used to inverse limits but it turns out to be the star of this paper: arxiv.org/pdf/1902.08887…

Actually it's not so bad: start with Hawaiian earring and loop L_n around the n-th circle. Attach pair of pants P_n to H where the belt of P_n is attached by L_n. One ankle is attached by L_{2n} and the other is attached by L_{2n+1}. It has some really fascinating properties pic.twitter.com/NLStuwzsGJ

From this, you can build the "Hawaiian Pants" space! twitter.com/memearcana/sta…

The property where clopen sets separate points is often called "totally separated" and is equivalent to the quasicomponents being points. The quasicomponents are not always the same as connected components. There does exist a totally disconn. space which is not totally separated.

Ronnie Brown shared this with me some time back and it's changed my life. If you're not using this to keep track of your citations, you're messing up.

CT is largely a service field in math. Dive deep into the depths of an area like AT/AG/GT/GGT/DG/CA that requires machinery from various fields. You'll wonder how you could possibly get by without the convenience of CT. It's value becomes implicit. But I doubt it'll do your taxes

My phone of 3 yrs died of natural causes today, which was upsetting. Tonight I went out and had a cigar and g&t in 65 deg weather only be distracted by my own thoughts. Pretty sure that was enlightenment. I'm sure I'll be tired of that crap by tomorrow when I pick up my new phone

I learned about the partition and Brauer monoids for the first time today at the UPenn Deformation Theory seminar. A bit combinatorial for my personal taste but the diagram calculus is so cool!

This sucks and these kinds of rejections hurt a ton but, no, this is not the answer. Find a way to channel some dirty hippies and be a little kinder to yourself.

I'm still communicating with Iranian topologists in respect and kindness despite the current political madness. I hope the nsa scanning the emails learns something about homotopy groups. #peoplearepeople

Going on a "math bender" is a real (and sometimes necessary) thing.

Very nice animation. It might be better to call this some kind of surgery though. A homotopy must be continuous, which would preserve path connectedness at each time step.

Advice to new math authors that should be obvious but apparently isn't. Write things in your own words! I've had multiple instances of authors copying sentences from introductions of my papers word for word🤨It's easy to recognize your own writing #plagiarism

After taking a little break from research, I have a full day tomorrow to work. Do I turn a mostly-finished project into a paper or spend all day on a shiny new problem that's caught my eye? pic.twitter.com/n7tEPciiUd
