Algebraic integers and surfaces dynamics McMullen, Curtis


The leading eigenvalue of an automorphism of a complex surface, acting on cohomology, associates an algebraic integer to each such dynamical system. In this talk we will discuss the reverse process: the synthesis of a dynamical system, starting with an algebraic integer. In particular we will explicitly describe dynamical systems of minimal entropy on K3 surfaces, rational surfaces and complex tori.
