Positve Entropy Geodesic Flows on Nilmanifolds
Leo T. Butler, Vassili Gelfreich
Let T be the nilpotent group of 4 x 4 real upper triangular matrices. In this note we show that the Euler equations of certain left-invariant riemannian metrics on T have a horsesh…

Magnetic flows on Sol-manifolds: dynamical and symplectic aspects
Leo T. Butler, Gabriel P. Paternain
We consider magnetic flows on compact quotients of the 3-dimensional solvable geometry Sol determined by the usual left-invariant metric and the distinguished monopole. We show tha…
