More concretely: Given a set of formulas Γ and a formula φ in some logic (e.g., first-order logic), Γ ⊨ φ means that every model of Γ is also a model of φ. On the other hand, fix a proof system (e.g., sequent calculus) for ... Witryna24. The existential quantifier " ∃x. ϕ(x) " in formal logic denotes "there exists at least one x that satisfies the property ϕ(x) ". If you're not writing very formally symbolic logic, you should also consider sticking to English, but just writing "some" instead of "at least one", as in.
