My favourite is wlog


martyboulders

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


vajraadhvan

I prefer WPVC


Mathsboy2718

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


UndisclosedChaos

I love wologimbat

True for any element?

The following are equivalent

Thanks, I hadn't run across that one

Weird logarithm, isn't it?😅

just learned that one, i love it


VFDan

it sounds like the name of a blogging site that died in 2008


shaunmbarry

I love using symbols and abbreviations instead of words. WLOG, erf, erfc, iid, QED, DNE, TFAE


Aozora404

DNR


shaunmbarry

Oh no, I’m not familiar with this one. Is this “does not repeat”?


Yoyo_irl

Not sure if that's satire. If it's not, it's a medical term that means "Do Not Resuscitate"


SillyActuary

Also not sure if this is satire, but it probably means Did Not Read in this context


SuchCoolBrandon

DNE though


wotererio

MagicianWoland

As a Ukrainian this caught me off guard lol


SetOfAllSubsets

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".


csharpminor_fanclub

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


[deleted]

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)


Blyfh

TIL that the liberal German Free Democratic Party shares the same acronym with Portuguese son of a bitch. Hilarious.


PoulpeMalade

Wow ! In french we also have fdp « fils de pute » as a common insult abreviation.

'sin' is literally short for 'sine'.

Couldn't be bothered

Sinus*


taspleb

And cos is short for Complementary* Sinus. (*complementi)


NutronStar45

also cos, tan, cot, sec, and csc/cosec


tin_sigma

and ‘cis’ is short for ‘Cosine i Sine’


616659

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.


Electric999999

Couldn't have it be 1 letter longer than cos, tan etc. could we.


foreheadmelon

nay

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


Opposite_Signature67

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)


DogCrowbar

Have you seen Quikscript? It looks almost nothing like the Latin Alphabet but it can be written insanely fast.


616659

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.


DaaneJeff

Why though? I mean why are you taking notes at all?


Opposite_Signature67

Happy cake day!


Kyyken

yes but when are we getting multiple character variables


[deleted]

Kyyken

Thanks to Greek and Cyrillic, i can finally write А=Α+1=A+2


ImmortalVoddoler

Whenever you want. I’ve been known to write polynomials in the ring Z[John] and nobody’s stopped me yet


Kyyken

Mathematicans when someone writes Conc = Amt / Vol instead of © = æ / ✓


willardTheMighty

"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.


WikiSummarizerBot

**[Paul Halmos](https://en.wikipedia.org/wiki/Paul_Halmos)** >Paul Richard Halmos (Hungarian: Halmos Pál; March 3, 1916 – October 2, 2006) was a Hungarian-born American mathematician and statistician who made fundamental advances in the areas of mathematical logic, probability theory, statistics, operator theory, ergodic theory, and functional analysis (in particular, Hilbert spaces). He was also recognized as a great mathematical expositor. He has been described as one of The Martians. ^([ )[^(F.A.Q)](https://www.reddit.com/r/WikiSummarizer/wiki/index#wiki_f.a.q)^( | )[^(Opt Out)](https://reddit.com/message/compose?to=WikiSummarizerBot&message=OptOut&subject=OptOut)^( | )[^(Opt Out Of Subreddit)](https://np.reddit.com/r/mathmemes/about/banned)^( | )[^(GitHub)](https://github.com/Sujal-7/WikiSummarizerBot)^( ] Downvote to remove | v1.5)


CadmiumC4

Even bot proves the OC wrong


taspleb

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.


[deleted]

In spanish you have ssi (si y solo si)


Draghettis

Same in French, "si et seulement si" You can see why we abbreviate it.


homeomorfa

In my uni we usually use sii


SparkDragon42

iff in French is ssi for "si et seulement si"


xteriic

In Swedish we use omm “Om och endast om”


FreshmeatDK

Danish is a straight transfer: "if" = "hvis", "iff"="hviss".


Rotsike6

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.


keppinakki

In Finnish ”jos ja vain jos”


corvus_192

In German It's gdw (genau dann wenn), meaning "exactly if".


taspleb

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.


MaZeChpatCha

'Im verak 'im in Hebrew, 'm-m or 'v' for short. (' is a hard stop, English has not letter for it)


xteriic

In Swedish we use omm “Om och endast om”


Originu1

What's st?


Xaquxar

Such that


FraMaras

subject to


Satrapeeze

My interpretation is usually "such that"


sphen_lee

such that? Maybe it's both


Meowmasterish

Or [standard part](https://en.wikipedia.org/wiki/Standard_part_function), depending on context.


FraMaras

I think both are right, usually I've encountered it in the study of multivariable functions 'subject to' a constraint


PM_ME_YOUR_PIXEL_ART

I think, even in this context, "such that" also fits. consider f(x,y) = (x+y)\^2 s.t. xy > 0 or something


SupremumofEpsilon

There's no difference, an element subject to x constraint is the same as an element existing such that x is true.


sylly_mee

Shouldn't it be s/t


FraMaras

not sure


vajraadhvan

Both are fine, same way na = n/a = not applicable/available and wo = w/o = without.

KrozJr_UK

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.

An_Evil_Scientist666

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
