I am writing a scientific paper. I need to express the intersection of two space, e.g. A and B where A and B can be a line, plane or a 3-D space. What is the appropriate symbol to state this concept. I used the intersections used in the set theory. Is it correct? Thank you! Amir

  • $\begingroup$ It's probably fine, but I suppose you could clarify it in the text (i.e., "…where the $\cap$ symbol means their intersections"), if you think some might find the notation unclear. $\endgroup$ – Akiva Weinberger Nov 18 '14 at 21:19

A line, plane or 3-D space are a set of points. So you could use the standard intersection symbol $\cap$ to take the intersection between any two sets.
