correct. everyone is allowed to create bad art. except me, however. i must contend with setting standards for myself i could never live up to

So, taking two *different* linear extensions, you get two different upper triangular matrices with an explicit permutation similarity. You can do a lot of simultaneous row&column swaps and manage to not mess up the matrix! 2/

Shower thought I find pretty entertaining: it's a standard argument that if c(λ,μ) > 0 iff λ ≥ μ in dominance order, c(λ,μ) packed in a matrix with rows, columns ordered by any linear extension of dominance is upper triangular, c.f, upper triangularity of Kostka numbers 1/

Friendship ended with analysis Now algebraic combinatorics is my best friend

passed my quals

A painting of hers I also like

"In field theory, a branch of mathematics, the Stufe(/ʃtuːfə/; German: level) s(F) of a field F is the least number of squares that sum to −1. If −1 cannot be written as a sum of squares, s(F) = ∞. In this case, F is a formally real field. Albrecht Pfister proved that the Stufe, if finite, is always a power of 2, and that conversely every power of 2 occurs."

just in: burritos are monads

an actual introduction since i can pin messages:

i'm jasper, a ph.d student @ drexel studying algebraic combinatorics.

my foundations are a bit swiss-cheesey since i wasn't a math undergrad (electrical and computer engineering), but i'm very very motivated, so everyone watch out

what the hell 😭

havent taken a shit since last year haha. also havent felt any fulfillment in life since 2005

I just found out there's a new Philomena Cunk series coming out next week and my heart is beating in anticipation much like the thumping beat of Belgium dance band Technotronic's 1989 hit single Pump Up The Jam

am but a neophyte but yes

a cool graph i looked at today. vertices are permutations of length 3 and edges are acb -> bac "rotation moves".

i'm really surprised that the sage graph plotter could automatically lay out the structure so nicely. a win graph drawing algorithms

omg a student somehow accidentally wrote an email addressed to a faculty-wide NYU listserv and my inbox is now a master class on who understands the difference between a listserv and an email chain

i believe this is an important image in our postmodern age

Will try to be here more because the other site is truly awful now. Please repost this so people can find me.

Dems: “But what can Biden even do about [student loan debt, climate crisis, abortion rights, ending the drug war, etc]??

“He has to work with congress, do you even know how government works you child? You imbecile? You Russian Troll? Grow the F up okay??”

5 min later:

we've had some disagreements, but we have healthy communication, and because of that, i think jasper is a great parent to our child yoyosweeper sasuke

hi introducing my tomodachi life spouse @clauds-chen.bsky.social to this atmosphere app. we have a son named yoyosweeper sasuke

a man gotta do what he yabba dabba do

sometimes when im alone at night i like to bite papers and pretend im a stapler
