Analytic Low-Dimensional Dynamics: a Celebration of Misha Lyubich's 60th Birthday May 27 - June 7, 2019 • Fields Institute Organizers: Anna Benini (Universitat de Barcelona), Tanya Firsova (Kansas State University), Petr Makienko (Instituto de Matemáticas, Unidad Cuernavaca), Scott Sutherland (Stony Brook University), Michael Yampolsky (University of Toronto) Analytic dynamics, a subject that has experienced explosive growth over the last few decades, studies the iteration of analytic maps, either real or complex, and the flows of systems of analytic differential equations, a closely related area. In this setting, many function-theoretic, geometric, and number-theoretic methods come into play. This conference took stock of the current activity in the field and charted new directions, and offered the chance to celebrate the 60th birthday of Misha Lyubich, one of the foremost experts in the field, whose vision has led to much of its development. The massive scale of the conference was a tribute to the major impact that complex- analytic methods have had on the study of low-dimensional dynamics over the last few decades. The two-week conference featured 40 invited speakers and attracted more than 150 visitors from over 20 countries. The conference structure featured talks by senior researchers, shorter talks from emerging researchers, poster sessions and unstructured time to foster informal mathematical exchange between participants. A beautiful synthesis of techniques has emerged, highlighting the interconnections between seemingly disjointed topics: the structure of the Mandelbrot set, the stochastic properties of a typical interval map, Feigenbaum-Coullet-Tresser universality and renormalization, among many others. It is difficult to overstate the relevance of Lyubich’s contribution to the field, both as a brilliant mathematician and as a charismatic leader who formed and influenced several of the most successful young researchers in the current generation, including his students and the many postdoctoral fellows who worked with him. At the Fields Institute in 2005-2006, Lyubich organized two notable semester-long programs which helped to launch many careers. Several conference participants engaged in those programs as postdocs or graduate students. Many of those he influenced spoke at the conference, and their talks spanned a wide range of topics inspired by Lyubich’s work: complex dynamics in one and several variables, Ising models, and holomorphic foliations. A significant group of the conference’s participants represent the new crop of young mathematicians, current postdocs and graduate students who will similarly benefit in their research progress from seeing the field through the eyes of the experts, and the wealth of Pictured: Participants in the Analytic open questions Dynamics and problems that Low-Dimensional Conference, including Misha were discussed.  Lyubich (front row, 9th from right). 17
