Invariants of two dimensional projectively Anosov diffeomorphisms
The author defines invariants of two-dimensional projectivity Anosov diffeomorphisms. The author shows that the space of circles tangent to the invariant subbundle has a kind of Morse decomposition. The author proves that the homotopy type of its one point compactification is preserved under any homotopy of projectivity Anosov diffeomorphisms, and presents calculation of the invariants for some examples.
