Rational surface automorphisms without periodic curves
John Lesieutre (Pennsylvania State University)
Abstract: Although there are many examples known of infinite-order automorphisms of rational surfaces, in most cases these automorphisms have at least one periodic curve C (a curve for which f^n(C) = C for some n). I will explain the construction of a class of rational surfaces which admit a large group of automorphisms with no invariant curves. The example makes use of several classical constructions, and the surfaces admit contructions down to three different Coble surfaces.
