MS1 Session Title: Multistability and Nonlocal Stability Analysis

Several dynamical systems are multistable: they exhibit a coexistence of stable solutions, formally called attractors. Examples include power grids, climate components, the brain, mechanical and metabolic systems, to name a few. Perturbations, such as noise or external shocks, can induce transitions between these attractors – which, depending on the application, may be either desirable or catastrophic. It becomes crucial therefore to study the stability in such multistable systems. Typically stability is studied using local bifurcation analysis and continuation, but this approach can be unsuitable for real-world applications where perturbations are finite-sized instead of infinitesimal. This calls for a nonlocal view of stability. Recent progress has enriched the literature with various quantities that can be used as quantifiers of nonlocal stability: basin stability or volume, the geometry of the basins, basin entropy, return time, minimal fatal shock, and other notions of resilience. In this minisymposium we want to highlight and promote recent research that explores one or several of the following categories:

– novel indicators of nonlocal stability
– novel techniques for finding multiple system attractors and/or their basins of attraction
– nonlocal stability analysis and continuation of multistable systems
– multistability in high-dimensional systems
– very high (10+) or extreme multistability (infinitely many coexisting attractors)
– multistability in chaotic systems

Neural networks and collective behavior represent leading research frontiers in complex systems theory. The human brain exemplifies a complex neural network, self-organizing into emergent states essential for its functions. Neural activity within individual nodes is often modeled using systems of ordinary differential equations. Such dynamical models offer a theoretical framework to explore the interplay between localized population dynamics and the intricate topology of brain networks, shedding light on overall brain activity. They also account for various forms of plasticity, such as synaptic and structural plasticity, and their influence on the system’s dynamics. This dynamical-modeling approach bridges concepts from mathematics, physics, and dynamical systems theory with empirically observed phenomena. For instance, it establishes connections between attractors, bifurcations, synchronization, and empirical neuroimaging data, including blood-oxygen-level-dependent (BOLD) signals from functional magnetic resonance imaging (fMRI). This mini symposium will feature expert-led discussions on the latest advancements in complex networks, collective behavior, synchronization phenomena, self-organization, neurocomputational platforms, and their diverse clinical applications.

Recent advances in time-series analysis have highlighted the value of ordinal patterns-based complexity quantifiers as robust tools for understanding dynamical systems. These measures, based on permutation entropy and other metrics applied to symbolic analysis of the time-series, provide a computationally efficient means of uncovering hidden patterns, underlying temporal symmetries, and regime changes in experimental data. Applications span diverse fields such as neuroscience, climatology, finance, quantum chaos, and photonics, including the characterization of time-series regularity, detection of transitions in complex systems, and classification of families of chaos.

In this mini-symposium we want to bring together researchers to explore the breadth of applications for these methods from across the fields listed above. Topics include, but are not limited to, the characterization of time-series regularity, detection of transitions in complex systems, and quantification of complex dynamics.

By focusing on both theoretical advancements and real-world implementations, this symposium aims to foster interdisciplinary dialogue and stimulate innovation in the analysis of experimental time-series data.

It is known that the same nonlinear system can perform synchronous oscillations or display asynchronous or disordered behavior, depending on some delicate differences in parameters and conditions. The synchronization can happen despite a disorder within the system, while synchronous oscillations can be spontaneously destroyed by internal instabilities. The synchronous and disordered dynamics can coexist. The goal of the minisymposium is to present the panorama of phenomena related to synchronization and desynchronization in networks of oscillators and oscillatory media, and elucidate their common features and dynamic patterns.

In the human organism, multi-component physiological systems, each with its own regulatory mechanism, continuously interact to coordinate their functions in an integrated network. The dynamics resulting from these interactions exhibits emergent patterns of synchronization or desynchronization which are associated with healthy or pathological states. Examples include tumor dynamics in physiological multilayer networks of organs and the immune system; brain network dynamics; psychiatric interactions of consciousness and decision making, among others. Often phase transitions and critical phenomena occur in such dynamical networks, leading to a plethora of partial synchronization patterns and complex collective behavior.

Reservoir computing leverages the response of driven dynamic systems for data-driven modeling, time-series prediction, classification, and control. Historically, recurrent neural networks have primarily served as dynamic reservoirs, but recent developments have extended this general approach to a variety of substrates, including passive and active optical systems, electro-optical systems, magnetic systems, memristors, spin wave systems, swarms, skyrmion textures, biological tissue, and quantum systems. A common goal of these investigations is to improve our theoretical understanding of various reservoir computing approaches and to achieve fast and energy-efficient hardware implementations. This minisymposium brings together experts across these areas to foster new ideas and cooperations which is vital towards advancing reservoir computing.

Machine learning tools have rapidly become integral to the analysis of data from dynamical systems, offering new perspectives on data-driven model development. While classical, theory-driven approaches may rely on simplifying assumptions, purely data-driven methods risk overfitting and can fail to illuminate understanding of the underlying dynamical relationships. Hybrid methods that integrate theoretical knowledge with data-driven components promise a new class of models and open opportunities for automation in the process of scientific discovery. Yet questions persist about how to interpret these models: Do they reveal or obscure key interactions and dynamics compared to more traditional approaches? And what is the scientist’s role in shaping and understanding such frameworks? This minisymposium invites contributions from across the sciences that employ machine learning and AI to identify relationships among dynamic variables and forecast future behavior. We welcome both theoretical and applied work, with the goal of fostering an interdisciplinary dialogue on the benefits, limitations, and emerging opportunities of machine learning for dynamical systems and real-world modeling applications.

Nonlinear waves are ubiquitous in natural systems ranging from fluid convection and vegetation systems to cardiac dynamics. Since these systems also naturally exhibit noise, the mathematical analysis of patterns and nonlinear waves in stochastic systems has received much attention over the last years. This minisympoium aims to bring together researchers from both stochastic analysis, dynamical systems, pattern formation, and nonlinear waves to present an overview of the field, give insight into recent results and identify open questions which can only be answered by combining the expertise of both communities.

Complex networks are pivotal in understanding a wide range of systems in physics, chemistry, biology, neuroscience, and socio-economic domains. Dynamical networks consist of interacting units that can exhibit complex collective behaviors and patterns. This minisymposium covers the following topics:
Adaptation / Co-evolution networks where the dynamics of the network and the dynamics on the network are interdependent are crucial for understanding synaptic plasticity, learning, neurodegenerative diseases, with applications in chemical, epidemic, biological, transport, social systems, power grids, and climate networks.
Higher order networks allow for direct interactions of more than two units. They provide a comprehensive framework for modeling complex systems, induce dynamical phenomena, and pose new challenges for their mathematical understanding.
Symmetries, bifurcations, phase reduction, and normal forms are important mathematical tools to investigate dynamical systems. Recently, there have been new developments to adapt them to specific types of network systems.
Synchronization control in neural networks: Many concepts of network dynamics find their application in neuroscience. Various methods for detecting and controlling synchrony are crucial in neural networks and neuroscience, with ongoing research offering potential for new discoveries.

The broad goal of modelling with dynamical systems is to construct differential equation-based formalisms to replicate observed data. Typically this is done using first principles methods by identifying underlying physical laws. Off late, data-driven techniques inspired by reduced order modelling and machine learning have been successful in learning dynamical systems directly from observed data, even when the state is not directly observed. Machine learning can also be leveraged to learn solution operators for PDEs with the physics-informed formalism. In this minisymposium we explore recent advances in domains such as kernel methods, forecasting, parameter identification and reduced order modelling.

The proposed mini-symposium aims at presenting some recent theoretical and experimental progresses on nonlinear, complex and chaotic dynamics in the field of photonics and phononics.
Chaos, instability, and nonlinear dynamics have attracted a lot of attention in recent years in photonics. Laser chaos induced by delayed optical feedback is one of them, and applied to, for example, generate Terahertz (THz) waves efficiently, This is an emergence of Chaotic Supremacy, the new concept to express superior functionality realized only by chaos. Optical bistable device with spatial expanse can also generate chaos using an external refractory feedback, that may achieve pulse network with chaotic time series. Also, in phononics, nonlinear dynamics provides interesting anomalous heat transport.
In view of such situation, we intend in this minisymposium to bridge various photonics and phononics researches including THz technology, nonlinear optics, and nonlinear phononics, to stimulate further studies in these research fields.

Title: Towards Data-Driven modeling of Habituating Systems

While a large body of work in nonlinear dynamics is devoted to the long-term behavior of complex systems in form of attractors, recent research emphasizes more and more that transient dynamics is of equal importance when we consider a large variety of phenomena like metastability, chimera states, rate-induced tipping or, more general, non-autonomous dynamical systems. Metastability refers here to a switching process between different dynamical regimes in state space with certain properties (e.g. periodic or chaotic), where each of these regimes lasts for a rather long but transient time before switching/transiting to another such regime. These transient phenomena as well as transitions between metastable states are often mediated by dynamical states of saddle character, such as saddle fixed points, saddle periodic orbits or chaotic saddles, which are the unstable counter parts of chaotic attractors. This minisymposium will discuss the emergence of long transients as well as metastability either related to the existence of chaotic saddles or to steady-states of saddle character, their statistical properties and their importance for various applications in complex systems. The minisymposium will also discuss concepts and methods to identify metastable regimes. The applications will address e.g. climate phenomena, collective motion of agents, neuronal systems, the dynamics of the heart, and ecosystem dynamics. Finally, we will also address the role of noise leading sometimes to extremely long transients.

Complex systems are characterised by the pathways of interactions between their constituents. However, traditionally, these have been reduced to only pairwise interactions, when considering polyadic interactions might actually be more true to the system. In fact, as has been established in the last several years, this crucially affects the system’s phenomenology and, particularly, its emergent dynamics. In this minisymposium, we will discuss recent work concerning and exploring the effects of polyadic or higher-order interactions.

Power grids are fundamental to modern society. Their many aspects, such as structural design, dynamic modeling, integration with renewable energy sources, or the management of supply-demand fluctuations, have provided a rich landscape for decades of research. Despite extensive studies, many questions remain open. The quest for answers has led researchers to new perspectives, together with the development of novel analytical and numerical methods. In this minisymposium, we explore such recent advances, specifically in power grid modeling and frequency dynamics, stability analysis, phase cohesiveness, synchrony, and control. We focus on current challenges like heterogeneity, unknown dynamics, renewable energy fluctuations, transient dynamics, and cascades. Bringing together researchers with different backgrounds, the minisymposium offers a variety of perspectives on power grids, including dynamical systems theory, machine learning, control theory, and optimization. This year we have decided to give center stage to early- and mid-career researchers.

Methods from nonlinear dynamics, complex systems, and information theory have enriched biosignal analysis, complementing and advancing traditional time series techniques. Significant progress has been made by applying these methods to the analysis of neural signals that characterize brain function. Measures of complexity, scaling, and entropy rates characterize brain dynamics, while measures of synchronization, dependence, and causality provide crucial insights into brain connectivity across different physiological and pathological states or assess the effects of therapeutic interventions. This minisymposium will showcase various methods inspired by nonlinear dynamics, applied in studies aimed at understanding changes in brain function in health and disease.
