ANOSOV DIFFEOMORPHISMS ON A CLASS OF 2-STEP NILMANIFOLDS
In this paper we study nilmanifolds which are modeled on a quotient of a free 2-step nilpotent Lie group by a 1-dimensional subgroup. In fact we obtain a very easy criterion to decide whether or not such a nilmanifold admits an Anosov diffeomorphism.(Received January 13 2002)
