Miscellaneous notes (not intended for publication)

  1. Limit points for tetrahedra and inscribed spheres An amusing, but elementary, result
  2. Estimating variance for expanding maps An unfinished note somewhat superceded by newer ideas
  3. A note on the arcsine law for geodesics A modest distributional result for geodesics
  4. Formulae for residues of Dynamical Zeta functions A note where the results didn't prove as useful as I hoped.
  5. Curvature of configuration spaces for planar linkages (with M.L.S. Magalhaes): A longer version of the published article.
  6. How to create chaos at home (with a 10 second movie and poster ) A poster on how to construct a chaotic linkage.
  7. Another account of the Dani-Smillie theorem An account I used in my Ergodic Theory course.
  8. Multiple mixing for hyperbolic flows A project I started (but never finished) during a Sabbatical.
  9. Large deviations, Gibbs measures and closed geodesics for rank one geodesic flows A modest result now out of date
