Discussion Overview

The discussion centers on the differences in usage between the phrases "so that" and "such that" within mathematical contexts. Participants explore the implications of each phrase in terms of grammatical correctness and their respective meanings in mathematical writing.

Discussion Character

  • Debate/contested
  • Conceptual clarification

Main Points Raised

  • Some participants assert that "such that" describes a condition that is already satisfied, while "so that" prescribes a condition that needs to be met.
  • One participant mentions that "so that" implies a purpose or result, whereas "such that" is more descriptive.
  • Another participant references a dictionary definition suggesting that "such that" is preferred, indicating a potential bias in usage.
  • Some argue that "so" implies a deduction or consequence, while "such that" can denote satisfaction of a condition.
  • One participant claims that "such that" applies to nouns and "so that" applies to verbs, suggesting a grammatical distinction.
  • There is confusion expressed regarding the correct usage, with some participants providing examples that they believe clarify the distinctions.
  • Alternative phrasing, such as "in such a way that," is suggested as a potential compromise in usage.
  • One participant notes that "such" may function similarly to a relative pronoun in this context.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the distinctions between "so that" and "such that." Multiple competing views and interpretations remain, with varying degrees of confidence in the correctness of each perspective.

Contextual Notes

Some participants express uncertainty about the implications of their explanations and the applicability of grammatical rules to mathematical language. The discussion reflects a range of interpretations and lacks definitive resolutions on the usage of the phrases.

"so that" and "such that"

Have a question about usage of mathematical jargon...
what are the differences between usage of "so that" and "such that"?

"z is a complex number such that Re[z]>0.": correct
"z is a complex number so that Re[z]>0.": wrong

but what about this case:

"Define z so that Re[z]>0"
"Define z such that Re[z]>0"

I really can't embarrass myself when I write mathematical papers. please help.

Perhaps someone has a more technical answer than this, but...

For me, "such that" means something is already a certain way and you're describing it, whereas so that means that something isn't a certain way already, but you're prescribing it. For instance...

"You have to study *so that* you will pass the test."
"You read a book *such* that it's 20 pages long."

Like, "so that" is a means to an end, and "such that" is just how it is.

I apologize if this isn't right. Somebody will be along to correct me.


In English, the difference between "so that" and "such that" is a much easier one to make, but I'm not sure it carries into the realm of mathematics. "such" is a word derived from "so much". "Such" deals with quantities, whereas "So" deals with qualities.
 


I looked up "such that" in the Collins concise English dictionary and the definition was:used to express purpose or result."So that",however, was adjacent to "such that" but not in bold type.It seems from this that either usage is correct.When I looked for
"so that" it wasn't entered.Because of the emphasis in the dictionary it seems that "such that" is the preferred usage.I,also,apologise if this isn't right.
 


"So" means "hence" - there should be a deduction: we choose X so that Y is true.

Or something like that, anyway. 'Such that' can also be used to mean 'satisfying' where it wouldn't be sensible to use 'so that'.

"Define z so that Re[z]>0": correct

"Define z such that Re[z]>0": incorrect

"Suppose there exists a complex number z such that Re[z]>0": correct

"Suppose there exists a complex number z so that Re[z]>0": incorrect
 


Grammatically, "such that" applies to a noun, "so that" applies to a verb. I believe that is also what Enuma Elish is saying.
 


im kinda confused because of different explanations

also, you can say "z is defined so that Re[z] > 0"
in other words, "so that" indicates an end, a purpose while such that just describes
does this sum up the correct usage?

Well there does seem to be confusion here and perhaps we are being too fussy.How about an alternative, for example...Z is defined in such a way that etc
 


"Such" seems to have a quality like a relative pronoun which can be used in combination with "that", working as a conjunction. HallsOfIvy gave the briefest and most useful characterisation. The "such" involved can be an idea having no concrete existence.
