Pseudo-Anosov maps and toral automorphisms
INFORMAL GEOMETRY AND DYNAMICS
Rick Kenyon - Yale University
We give a construction of a pseudo-Anosov map of a surface starting from (and almost isomorphic to) a hyperbolic automorphism of an n-torus. The construction arises from a peano curve based on an invariant space-filling tree. This construction allows to confirm (for degree 3) a conjecture of Fried regarding stretch factors of pseudo-Anosov maps.
