Abstract
We construct a C ω C^\omega diffeomorphism of the 3-torus whose rotation set is not closed. We prove that the rotation set of a homeomorphism of the n n -torus contains the extreme points of its closed convex hull. Finally, we show that each pseudo-rotation set is closed for torus homeomorphisms.
