A key challenge of nonlinear dynamics and network science is to understand how higher-order interactions influence collective dynamics. Although many studies have approached this question through linear stability analysis, less is known about how higher-order interactions shape the global organization of different states. Here, we shed light on this issue by analyzing the rich patterns supported by identical Kuramoto oscillators on hypergraphs. We show that higher-order interactions can have opposite effects on linear stability and basin stability: They stabilize twisted states (including full synchrony) by improving their linear stability, but also make them hard to find by markedly reducing their basin size. Our results highlight the importance of understanding higher-order interactions from both local and global perspectives.

3rd Meeting of the Spanish Society of Complex Systems

February 19-21, 2025. Puerta de Toledo Campus, Carlos III University of Madrid

During the 2022 International Conference on Complex Systems held in Palma de Mallorca, the Complex Systems Society approved the creation of its Spanish Chapter .

The main objective of the Spanish Chapter is to bring together researchers in complex systems and other areas of potential interaction at an annual meeting held somewhere in Spain. The Chapter has held two meetings, the first in Santander in May 2023 and the second in Barcelona in February 2024 .

This 3rd meeting will take the form of a two-day workshop, starting on Wednesday, February 19 at 3:30 p.m. and ending on Friday, February 21 at 2 p.m. There will be approximately 5 invited talks (30 minutes each) and several contributed talks (15-20 minutes), plus a poster session.

The Squiggle Sense: Sixth Sense of the Complementary Nature and the Metastable Brain~Mind, by J. A. Scott Kelso & David A. Engstrøm

Either/or thinking is a major stumbling block to human development and understanding. In this book Kelso & Engstrøm offer a whole new way of looking at the world, awakening a “sixth sense” that people didn’t realize they had. It draws on the profound relationship between nature’s many complementary contraries and the paradigm shifting science of coordination called Coordination Dynamics. The human brain~mind, through the multi- and metastable modes of its coordination dynamics, gives rise to a sentient faculty called the squiggle sense. Nature’s contraries are perceived not only as opposing polar states, but as coexisting complementary tendencies, symbolized by the squiggle (~). Use this book to nudge your brain~mind into its metastable mode again and again, to better perceive the complementary dances of contraries, and to transcend the detrimental narrow-mindedness of polarized, either/or thinking. As a “Metastabilian” you can wield your squiggle sense to enhance and advance your life!
