Beatty's theorem in rings of integers?
Posted:

Beatty's theorem states that if a and b are positive irrational numbers satisfying 1/a + 1/b = 1, then {floor(na)  n in N} and {floor(nb)  n in N} partition the positive integers N into two disjoint sets. Is there a generalization of this to rings of algebraic integers? It is not even clear to me how to formulate the question precisely, but something like this seems to be what I need for another problem I'm working on.
