Main areas are dynamics of automorphisms (for example, Henon maps), dynamics of endomorphisms, dynamics of foliations, and local dynamics.
Eric Bedford, Tien-Cuong Dinh, John Fornaess, Misha Lyubich, Nessim Sibony, John Smiley, and their students and collaborators.
One-dimensional holomorphic dynamics, functions of several complex variables (especially holomorphic maps and currents), basic complex algebraic geometry, and basics of the general theory of dynamical systems.
