Minisymposia

Call for minisymposia

The call for organizing Minisymposia is opened. Interested organizers may send their proposal to ddeu2025@auth.gr

The proposal should contain

1.  Names, affiliations and contact details of organizers.

2. Title and a short description (one paragraph) for the topic of the proposed minisymposia.

3. A tentative list of potential speakers (names and affiliations).

A minisymposium should have a total duration of 120min. It may have 4 talks of 30 min duration (25 min presentation plus 5 min for questions), but other forms may be suggested as well, e.g. 6 talks of 20 min duration (17  min presentation plus 3 min for questions). A minisymposium may have more than one two-hour session, e.g., part I and part II. 

List of minisymposia

The following minisymposia will take place in DDE2025. The exact dates/times will be added when the program is announced. Please note that as for now the list of speakers is tentative.

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

Focused on future research directions for modeling the spread of pathogens capable of causing new outbreaks, this interdisciplinary symposium aims to promote timely debates exploring various approaches in epidemiology, particularly on the mathematical modeling of infectious respiratory and vector-borne diseases. Key discussions will cover recent advances in mathematical epidemiology, offering a comprehensive look at both theoretical methods and practical applications. Topics will include the role of temporal and spatial dynamics in disease transmission, the challenges of predicting epidemic trends, improving predictive models to inform public health strategies, and the integration of environmental and human behavior factors into models. By bridging theory and practice, the symposium aims to enhance tools for disease control and outbreak preparedness.

MS3 Session Title: Quantum chaos in few and many body systems

Session Organiser:
Robnik, Marko, CAMTP – Center for Applied Mathematics and Theoretical Physics, University of Maribor, Maribor, Slovenia
email: marko.robnik@guest.um.si

The talks will cover the topics on most recent results in quantum chaos of few and many body systems. We shall address the semiclassical behavior of quantum systems, and their correspondence to the associated classical chaotic systems, as well as the studies of quantum systems without a classical analog. In particular, we shall focus on the following aspects: spectral statistics, phase space localization of eigenstates, the statistical properties of the localization measures, ergodicity properties and their hierarchy, dissipative quantum systems, localization and thermalization, time evolution, in particular studies of OTOC (out-of-time order correlators). Several model systems will be presented and analyzed, on which the phenomenological results are based, as well as they are a basis for theoretical approaches.

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.
