We show that a smooth compact Riemannian manifold of dimension 2 admits
a Bernoulli dieomorphism with nonzero Lyapunov exponents.
Transitions in active rotator systems: invariant hyperbolic manifold approach

Our main focus is on a general class of active rotators with mean field interactions, that is globally coupled large families of dynamical systems on the unit circle with non-trivial stochastic dynami...

Let M3 be a closed hyperbolic three manifold. We show that the number of genus g surface subgroups of 1(M3) grows like g 2g.
