The Dynamical Degrees of Rational Surface Automorphisms

Kyounghee Kim

The induced action on the Picard group of a rational surface automorphism with positive entropy can be identified with an element of the Coxeter group associated to …

An Automorphism group of a rational surface: Not too big not too small

Kyounghee Kim

This article concerns the realization problem of subgroups of Coxeter groups. We construct a subgroup of the Coxeter group such that is realized as automorphism gr…

Entropy of real rational surface automorphisms: Actions on the Fundamental Groups

Kyounghee Kim, Eric P. Klassen

This article discusses a method to compute the induced action on the fundamental group of a real rational surface and provides the induced actions for basic quadratic real automorp…

Entropy of real rational surface automorphisms

Jeffrey Diller, Kyounghee Kim

We compare real and complex dynamics for automorphisms of rational surfaces that are obtained by lifting \chg{some} quadratic birational maps of the plane. In particular, we show h…

Julia sets for polynomial diffeomorphisms of are not semianalytic

Eric Bedford, Kyounghee Kim

For any polynomial diffeomorphism of with positive entropy, neither the Julia set of nor of its inverse is semi-analytic.

No smooth Julia sets for polynomial diffeomorphisms of with positive entropy

Eric Bedford, Kyounghee Kim

For any polynomial diffeomorphism of with positive entropy, neither the Julia set of nor of its inverse is smooth as a manifold-with-boundary.
