I'm about to publish my first coauthored paper soon. I only contributed 3-4 pages out of ~20, but it still feels surreal. Just a year ago I didn't think any mathematician would've seen something in me to give me this opportunity, especially considering my undergrad grades. (1/4)

I had 38 seconds on the clock when I got to this position in a bullet game. Can you find the forced checkmate within this time? (I didn't - chat, am I cooked?) #chesspunks

I don't understand the intuition behind comultiplication in (co/bi)algebras. Yes I'm aware that it's the dual of multiplication, but categorical duality means nothing to me in terms of intuition. Is there a better explanation of how to find an expression for Δ(x) given μ? #mathsky

Why is so little known about the representation theory of the symmetric group over positive-characteristic fields? #mathsky

This trend has been going viral on tw*tter so I'll cross-post my entry here as well. Four math books that had a big influence on my mathematical thinking. Your turn. #MathSky #AlgComb

Symmetric function theorists: Since the plethystic substitution & evaluation maps don't commute in general due to an extra factor of (-1)^n involved when evaluating the plethysm of a negation (a problem when n is odd), would a characteristic 2 setting solve this problem? #MathSky #AlgComb

ik bluesky isn't the best place for this but I really wanna find this earworm. All I know is that it's probably mando/canto/J-pop, in B♭ major, and notoriously repeats the chord progression Ia-Vb-via-Ic-IVa-Ib-ii7a-Va with these exact inversions throughout the whole song. Ideas?

I hate YouTube's automatic translations because they often suck and I don't know how to turn them off I don't think this guy was literally murdered in front of the judge. That seems unlikely

i HATEEEEE to do this, but this is all i currently have to my name, so if you enjoy my posts at ALL and wanna support a struggling grad student, please share and/or give what you can 🥹 v e n m o: astrojaz p a y p a l: www.paypal.me/Spacequeenjaz

Btw if you read this far give this post (not the first one) a like. Bluesky is notorious for only showing people the first message in a thread and consequently people only interact with the first message, so I want to see how many people actually read the whole thing. That's all for now. (12/12)

Oh yeah so I turned 22 yesterday. I don't usually like birthdays because it's a painful reminder that I've yet again wasted another year of my life accomplishing nothing. I'm working hard on changing that though, which is why I haven't been posting much lately. (1/12)

I submitted finalish drafts of Chapters 1-6 of "Visual Algebra" to the AMS, and have stable drafts of the other chapters. Is anyone interesting in reviewing it? Either formally or informally. I'm sure the AMS offers something for such a service, like book credit. 1/2

Any combinatorial peeps I can follow on #MathSky? Just getting started and already in love with the subject.

My institute, Kavli-IPMU at the university of Tokyo is hiring early career researchers whose work has been disrupted due to difficult circumstances due to events happening at various places currently in the world. Please repost and encourage them to apply. 🙏🏻 www.ipmu.jp/en/job-oppor...

oh no, we hebben again een serieus probleem

Think imma do a Q&A I'll try to answer all questions over the next week or so, but if I don't like the question (e.g. because it's too personal) then I'll skip it ngl.link/totientquoti...

In graph theory, there is something called "Scheinerman's conjecture." It was proven in 2009, so it's not a conjecture anymore, but it's been known by that name for so long that nobody wants to call it anything else.

I have been working with Chebyshev polynomials a lot recently. I barely know any other polynomials anymore

Any piano teachers here willing to help me for money? I can't do lessons but I do think being able to commission audio would help me.

#AcademicSky I'm so tired of being misunderstood. Every time I talk about how people should be more sympathetic to those struggling in an intense program, people reply with accusations of elitism and privilege blindness. They then double down on how I fully deserved to struggle, 1/2

I hope to find a partner equally obsessed with algebraic combinatorics in the future. Maybe, just maybe, we'll be able to find a Littlewood-Richardson rule for multiplying two Schubert polynomials at some point. #MathSky #AlgComb

#MathSky #AcademicSky Now that I've heard back from many of my grad school applications, I'd like to complain about the collective lack of interviews. How can uni departments accurately assess one's fit for the program without having conversed extensively with the applicant? 1/3

#mathsky #iteachmath just throwing out my portfolio if anyone is interested in commissioning any mathematical visualizations

I had the privilege of serving as a part-time federal expert for the National Science Foundation, until today. www.linkedin.com/posts/courtn...

Everyone bumping Not Like Us and yes it is definitely a hit, but the beat off 6:16 in LA is definitely so hypnotising and got me hooked

Quoteposting with some images, but below is a thread of some of the projects I'm most proud of 🧵 (also I'm looking for work)

I'm looking for my next software engineering role. If you need someone to make intricate cool visualizations (or anything really) send me a DM! A couple of my projects: tesseralis.site

Finished all my courses for my masters degree. Now the only thing left is "just" my thesis. Will be tough but we will see where it takes me :)

So satisfying when you prove something for your thesis that hasn't been proved or at least you couldn't find the proof online :)

Reading about Generalised Tree Shift and seeing that it makes a poset is such a surprising thing to read about. It is so cool

Pattern blocks in the angled mirrors by Laura at #100factorial today.

My brain is dead after a 3 hour exam. It is so tiring

The different worlds of doubly discrete strange attractors #art #science #mathematics #mathsart

Love this! Everyone should strive for this when in a position to influence others

For all my life, I've been constantly reminded that I have the lowest achievement-to-effort ratio in my circle. It's disheartening enough working my ass off just to see marginal improvement, let alone having to deal with insults like "all passion no talent", "tortoise humiliated by hares". 1/12

This is what I wish to change. I believe that ordinary people can also accomplish extraordinary feats, that you don't have to be in the top y% to achieve something meaningful, that you can be a tortoise instead of a hare and still cross the finish line. 7/12

#MathSky #AlgComb The automorphism group of the Cartesian product of connected prime graphs is isomorphic to the aut group of the disjoint union of the prime factors. Is there a category-theoretic explanation? In the category of sets, ⊔ is dual to ×. Is there something similar in the cat of graphs?

#MathSky #AlgComb Any algebraic combinatorialists (incl. algebraic graph theorists) here? Would like to know more people in the field I'm most interested in, and possibly make an algcomb starter pack here. Non-algcomb people welcome too as long as there's interest in discussing algcomb topics.

I usually love the structure of the Dutch mathematics masters but something that always irked me is the exam month after Christmas break, i.e. you will probably need to study during the break otherwise you might fail your exams directly after the break

I had the privilege to speak to one of my followers who has a PhD in mathematical physics. It was very inspiring to talk to someone like that. Anyone open to chat over voice or DMs about their math research or PhD, please do reach out. I'd love to get to know more people. 😍

#MathSky 🧵 Solution: The order of the group follows from the fact that for a matrix of the required form, the entries on or below the diagonal are fixed and the ones above, which there are n(n-1)/2 of, can each be freely chosen from the elements of ℤ/pℤ. As for the group axioms, (1/9)

Hi everyone! I come from Twitter to here, here for #mathsky however I am usually not one posting content myself. I do love to read all about what others are doing. Did my bachelors in Utrecht and now doing the masters. Soon starting with my masters thesis :)
