WAVECOMPLEXITY

Fostering cross-disciplinary progress on complex wave phenomena

Background

Nonlinearity, disorder and multiple scales are all sources of complexity for wave phenomena. Addressing complex wave phenomena from detection to forecasting or modelling, from microscopic to physiologic and astronomical scales requires a very broad spectrum of expertises. In turn, progress in understanding complex wave phenomena is key for the fundamental aspects of complexity science and for our capacity to face present and upcoming environmental risks. The WAVECOMPLEXITY initiative, funded by Université Côte d’Azur through Academy 2 “Complex Systems” and Academy 3 “Space, Environment, Risk and Resilience” aims at fostering cross-disciplinary scientific progress in the realm of complex wave phenomena.
