Article Abstract
Watanabe-Strogatz theory provides a low-dimensional description of identical Kuramoto oscillators via the framework of the Möbius transformation. Here, using the Watanabe-Strogatz theory, we provide a unifying description for a broad class of identical Kuramoto oscillator models with pairwise and higher-order interactions and their corresponding higher harmonics. We show that the dynamics of the Watanabe-Strogatz parameters are the same as those of the mean-field parameters. Additionally, the poles of the Möbius transformation serve as basin boundaries for both global and cluster synchronization in the models discussed here. We present numerical simulations that illustrate how the basin boundaries evolve for these extended models.

The Kuramoto model, a paradigmatic framework for studying synchronization, exhibits a transition to collective oscillations only above a critical coupling strength in the thermodynamic limit. However, real-world systems are finite, and their dynamics can deviate significantly from mean-field predictions. Here, we investigate finite-size effects in the Kuramoto model below the critical coupling, where the theory in the thermodynamic limit predicts complete asynchrony.

Network inference, which involves reconstructing the connectivity structure of a network from recorded data, is essential for broadening our understanding of physical, biological, and chemical systems. Although data-driven network inference algorithms have made significant strides in recent years, determining how much data is required so that the inferred network topology faithfully mirrors the underlying network remains an essential but often overlooked subject. In this paper, we present a statistical method to determine whether the recorded data carries sufficient variability to ensure an accurate reconstruction of the true network topology.

Coupled oscillators can serve as a testbed for larger questions of pattern formation across many areas of science and engineering. Much effort has been dedicated to the Kuramoto model and phase oscillators, but less has focused on oscillators with variable amplitudes. Here, we examine the simplest such oscillators-Stuart-Landau oscillators-and attempt to elucidate some puzzling dynamics observed in simulation by us and others.

The exploration of the intrinsic mechanisms underlying synchronization has long held pervasive significance within the scientific community, as it offers profound insights for understanding the macroscopic self-organized dynamics on top of complex systems. Here, we investigate the generalized Kuramoto model incorporating the mixed higher-order interactions. In particular, we mathematically argue that, in the mean-field representation, the coupling scheme is equivalent to the biharmonic coupling, wherein the coupling function of phase oscillators goes beyond the setting of the single-Fourier modes.
