Difference between "≈", "≃", and "≅" - Mathematics Stack Exchange

https://math.stackexchange.com/questions/864606/difference-between-%E2%89%88-%E2%89%83-and-%E2%89%85
In LaTeX it is coded as \cong. ∼ ∼ is a similarity in geometry and can be used to show that two things are asymptotically equal (they become more equal as you increase a variable like n n ). This is a weaker statement than the other two. In LaTeX it is coded as \sim. ≃ ≃ is more of a grab-bag of meaning.

I think it's probably just notation to distinguish the ordering on F F from that on E E. Other acceptable symbols include ⪯ ⪯, ⊑ ⊑, etc. To explain what they mean by X ⪯ Y ⇔ X = X ∧ Y X ⪯ Y ⇔ X = X ∧ Y, they are referring to the Meet of X X and Y Y. You have x ∧ y = z ⇔ z ⪯ x x ∧ y = z ⇔ z ⪯ x and z ⪯ y z ⪯ y.
