A two-week summer school in the summer 2023 that addresses the description/characterization/analysis and modeling of complex and/or scale-free temporal/spatial dynamics in functions, processes, images and fields..., under the light of several scientific fields, ranging from theoretical and methodological developments to real-world applications. The program will start from harmonic and fractal analysis as developed by mathematicians and will progressively introduce a variety of real-world applications (very different in nature, yet with a focus on neurosciences and neurophysiology towards the end of the workshop) via statistical signal and image processing and computer sciences.
