Abstract We consider the continued fraction expansion of real numbers under action a nonuniform lattice in $\text {PSL}(2,{\mathbb R})$ and prove metric relations between convergents natural geometric notion good approximations.

This paper provides an overview of a workshop on the implementation of a tested phonological therapy model, and complements handout materials for workshop participants. The workshop focuses on the practicalities of administering the therapy against a background of its theoretical origins, clinical development and validating research (Bowen, 1996). Emphasis is placed on the value of published cl...

We consider partially hyperbolic diieomorphisms preserving a splitting of the tangent bundle into a strong-unstable subbundle E uu (uniformly expanding) and a subbundle E c , dominated by E uu. We prove that if the central direction E c is mostly contracting for the diieomorphism (negative Lyapunov exponents), then the ergodic Gibbs u-states are the Sinai-Ruelle-Bowen measures, there are nitely...
