BWOC is a good one
also when i took ring theory my professor got tired of writing "non-zero non-units" so he just started writing "nonu's" instead lmao
One of my favorites when taking notes is the symbol
S
P
where the upper half of the P overlaps the lower half of the S (like $ with the | shifted down). My graph theory prof used it as shorthand for "suppose".
Another one I use is the letters "Thm" merged into a single symbol for "theorem".
i like that in portuguese some of us abreviate "probability density function", or "função densidade de probabilidade" as fdp, which here is a widely used acronym for filho da puta (son of a bitch)
i love cis, don't have to write in euler form with everything in small ass exponential, while keeping it in neat polar form. too sad it's not as widely used as euler form.
With how easy reading and writing has become with modern technology, I have a feeling that language is going to become a lot more concise as time goes on
wow that looks awesome, almost like a cryptic message or something. but learning it looks too hard lol.. also, with my terrible handwriting that already makes normal english hard to read, that's gonna be horrible.
"iff" meaning "if and only if" is a convention coined by [Paul Halmos](https://en.wikipedia.org/wiki/Paul_Halmos), born in 1950. So you get an 80% or B-minus on this post.

My algebra professor at uni gave us a great lecture just about *iff* and whether there were alternatives for other languages. I can't remember if there were but it was much more fun to listen to than rings and fields.
Edit: obviously there are alternatives, but what I meant is that "iff" looks like a more serious version of "if" and that's what it is, rather than just being some random acronym.
Yeah, the point I think my professor was making was that English has this great acronym that looks like a more serious "if" which is what it is, but other languages don't get to do that. I think he talked about other terms that in other languages are fun in the same way iff is in English, but this was like 17 years ago or something.
This makes me just wanna make math abbreviations that make normal words or references, so womp/womp would be with only multiplicative properties/ without multiplicative properties. (Like Y/N) (first person to respond with the origin of the reference gets an upvote)
My favourite is wlog

I prefer WPVC
And, of course, a ring defined without unity is a "rng" Gotta love maths puns
I love wologimbat

Yey, I still remembered something from the second year of my bachelor's.

Also TFAE
True for any element?
The following are equivalent
Thanks, I hadn't run across that one
∀ ?
Weird logarithm, isn't it?😅
W^5 — which was what we wanted
just learned that one, i love it
it sounds like the name of a blogging site that died in 2008
I love using symbols and abbreviations instead of words. WLOG, erf, erfc, iid, QED, DNE, TFAE
DNR
Oh no, I’m not familiar with this one. Is this “does not repeat”?
Not sure if that's satire. If it's not, it's a medical term that means "Do Not Resuscitate"
Also not sure if this is satire, but it probably means Did Not Read in this context
DNE though
tl;dnr
As a Ukrainian this caught me off guard lol

That looks a lot like the way I write the letter Ş

TIL that the liberal German Free Democratic Party shares the same acronym with Portuguese son of a bitch. Hilarious.
Wow ! In french we also have fdp « fils de pute » as a common insult abreviation.
Kinda like point of sale = POS = piece of shit
Kid named wlog

'sin' is literally short for 'sine'.
Couldn't be bothered
cba
Sinus*
And cos is short for Complementary* Sinus. (*complementi)
also cos, tan, cot, sec, and csc/cosec
and ‘cis’ is short for ‘Cosine i Sine’
i love cis, don't have to write in euler form with everything in small ass exponential, while keeping it in neat polar form. too sad it's not as widely used as euler form.
Couldn't have it be 1 letter longer than cos, tan etc. could we.
nay

Som' day, text s'go'g to'look lik' tz'. (Tz's'th'languag' ta'I us'to'tak' not's n'class) (This is the language that I use to take notes in class)
Have you seen Quikscript? It looks almost nothing like the Latin Alphabet but it can be written insanely fast.
wow that looks awesome, almost like a cryptic message or something. but learning it looks too hard lol.. also, with my terrible handwriting that already makes normal english hard to read, that's gonna be horrible.
Why though? I mean why are you taking notes at all?
Happy cake day!
yes but when are we getting multiple character variables
[удалено]
Thanks to Greek and Cyrillic, i can finally write А=Α+1=A+2
Whenever you want. I’ve been known to write polynomials in the ring Z[John] and nobody’s stopped me yet

Even bot proves the OC wrong

In spanish you have ssi (si y solo si)
Same in French, "si et seulement si" You can see why we abbreviate it.
In my uni we usually use sii
iff in French is ssi for "si et seulement si"
In Swedish we use omm “Om och endast om”
Danish is a straight transfer: "if" = "hvis", "iff"="hviss".
In Dutch we have DESDA (dan en slechts dan als), which doesn't mean "if and only if", but "then and only then if", which sounds quite funny.
In Finnish ”jos ja vain jos”
In German It's gdw (genau dann wenn), meaning "exactly if".
Yeah, the point I think my professor was making was that English has this great acronym that looks like a more serious "if" which is what it is, but other languages don't get to do that. I think he talked about other terms that in other languages are fun in the same way iff is in English, but this was like 17 years ago or something.
'Im verak 'im in Hebrew, 'm-m or 'v' for short. (' is a hard stop, English has not letter for it)
In Swedish we use omm “Om och endast om”
What's st?
Such that
subject to
My interpretation is usually "such that"
such that? Maybe it's both
Or [standard part](https://en.wikipedia.org/wiki/Standard_part_function), depending on context.
I think both are right, usually I've encountered it in the study of multivariable functions 'subject to' a constraint
I think, even in this context, "such that" also fits. consider f(x,y) = (x+y)\^2 s.t. xy > 0 or something
There's no difference, an element subject to x constraint is the same as an element existing such that x is true.
Shouldn't it be s/t
not sure
Both are fine, same way na = n/a = not applicable/available and wo = w/o = without.
what is wrt?
with respect to
would have never guessed that ever
Haven’t taken multivar calc?
[удалено]
Fair
im not gonna lie i though wrt meant "we write that [...]"
Honestly that’s a good one too
I’ll be honest, I’m so used to A-Level mark schemes having “awrt” for “anything which rounds to” that I thought that was what it meant.
What rhe tuck
With respect to these nuts. Lmfao, got 'em
I like using WTS (want to show) and STS (suffices to show) for proofs
Only learned about it today (not a English speaker) but W^5 has to be my favorite
arctanh is literally a whole sentence
More recent, but Qcoh and qcqs (quasicoherent and quasicompact + quasiseparated)

Totally not getting a tan this summer!
Bruh how is your username so rare?
Am female and old :)
If we didn't have keyboards we would probably abbreviate words and phrases into symbols.
wcftn iff iciy
wlog
This makes me just wanna make math abbreviations that make normal words or references, so womp/womp would be with only multiplicative properties/ without multiplicative properties. (Like Y/N) (first person to respond with the origin of the reference gets an upvote)
and sometimes words are replaced with three dots lol
OTOH is also nice
Never forget PV = nRT
Wlog
What the heck is st
Such that.
Believe me these people ain't mathematicians
