Synchronizations in Complex Systems Dynamics Through a Multifractal Procedure [PDF]
EntropyThe dynamics of complex systems often exhibit multifractal properties, where interactions across different scales influence their evolution. In this study, we apply the Multifractal Theory of Motion within the framework of scale relativity theory to ...
