Aug 22, 2011 at 19:49 comment added fedja Yes, it is $i$ (square root of $-1$) times the usual scalar product of $x$ and $y$. This time I was just a bit lazy to type langle and rangle and thought that the (,) notation would do. Well, a lazy person does everything twice, indeed :). Today I also noticed that just the hyperplane condition isn't quite enough but I'll be almost equally happy with "not contained in finitely many hyperplanes" or "has a point no neighborhood of which is contained in a hyperplane" as a condition.

Aug 21, 2011 at 21:10 comment added Anthony Quas presumably exp[ i * <y,x> ] where <y,x> is the standard Euclidean inner product?
Aug 21, 2011 at 17:07 comment added Thierry Zell Could you clarify what is meant by $e^{i(y,x)}$?
