概要
Automorphisms of complex surfaces can have various invariant curves. In this talk, we consider a family of rational surface automorphisms with an invariant caspidal cubic curve.
Such rational automorphism can have, at he same time, an invariant line, or an invariant quadratic curve, or a pair of lines intersecting at a point.
Dynamics in invariant curves are studied.
