Which symbol stands for such that?
The symbol ∃ means “there exists”. Finally we abbreviate the phrases “such that” and “so that” by the symbol or simply “s.t.”. When mathematics is formally written (as in our text), the use of these symbols is often suppressed.

When to use ” such that ” in a set?
In sets though, like set-builder notation, both ∣ and : are used: “The set of all x ∈ R such that x < 0. {g ∈ G: Φ(g)} is the set of those g in G if Φ is true.
