The Hyperbolic Heisenberg and Sigma Models in (1+1)-dimensions
  Hyperbolic versions of the integrable (1+1)-dimensional Heisenberg Ferromagnet and sigma models are discussed in the context of topological solutions classifiable by an integer `winding number'. Some explicit solutions are presented and the existence of certain classes of such winding solutions examined.
