Complex dynamics concerns the iteration of analytic functions of one complex variable, an area of research established by Fatou and Julia towards the beginning of the last century, with Fatou’s seminal paper on the iteration of transcendental functions published in Acta Mathematica in 1926. This is now a highly active area of research with rapidly growing interactions with several other areas of mathematics. This workshop provides an opportunity to explore and celebrate the legacy of the last hundred years, and to identify the topics and interactions of most interest as we move into the next hundred years.
