1 Answer. Sorted by: 17. It's hard to tell without a bit more context (and since I don't know what an iso-intensity surface is). But I think it would more commonly be written R2 R 2, which is the set of pairs of real numbers. So my guess would be that saying (x, y) ∈ R2 ( x, y) ∈ ℜ 2 just means that x x and y y are both real numbers ...

Mathematical symbols use a roman, serif font (½, +, √, cos) — except when they are applied to calculations with units.
