Call for minisymposia
The call for organizing Minisymposia is opened. Interested organizers may send their proposal to ddei2025@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.

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
