Scientific Calendar Event



Description
The study of nonlinear systems continues to yield new and fascinating phenomena. Recently, a striking development has emerged in complex systems research: bringing together concepts from statistical and nonlinear physics allowed for the prediction and discovery of a novel effect,  called the chimera state.  Chimera states are a nice example of unexpected, counterintuitive dynamics where the interplay of synchronization, long-range interactions and pattern formation mechanisms are essential.

The aim of the school is to review the progress in this field, where physics and applied mathematics strongly overlap with life sciences; find new interconnections and general analytic, numerical, and statistical approaches; and identify novel directions and cross-disciplinary applications. The targeted audience includes advanced undergraduate and PhD students, as well as post-doctoral fellows and junior researchers. Special attention will be devoted to the training of scientists from developing countries in line with the fundamental mission of the AS-ICTP.
 
The workshop brings together a mix of world-leading experts in the field and young researchers to cover most important recent achievements in understanding of complex structures and the nature of synchrony in nonequilibrium systems.
