The Degree of the Inverse of a Polynomial Automorphism
Let F : C → C be an invertible map for which both F and F−1 are polynomials. Then deg F−1 ≤ (deg F )n−1. This is a well-known result. The proof that we give here, at least for low n, does not depend on advanced algebraic geometry.

15 صفحه اولThe expansion factors of an outer automorphism and its inverse
A fully irreducible outer automorphism φ of the free group Fn of rank n has an expansion factor which often differs from the expansion factor of φ. Nevertheless, we prove that the ratio between the logarithms of the expansion factors of φ and φ is bounded above by a constant depending only on the rank n. We also prove a more general theorem applying to an arbitrary outer automorphism of Fn and ...
