Nonlinear Dynamics Team

Lenka Přibylová presented the Nonlinear Dynamics Team at the research exhibition organized on the occasion of the International Day of Women and Girls in Science at the Faculty of Science, Masaryk University. The talk highlighted how nonlinear dynamical systems help uncover crucial transitions in complex phenomena ranging from physical systems to neuroscience. You can see the presentation here. See program.

In February, Jan Ševčík successfully defended his doctoral dissertation devoted to synchronization phenomena in dynamical systems from the bifurcation theory perspective. The work investigated synchronization and multistability in small and larger networks of coupled neurons, analyzing their collective dynamics through a rigorous dynamical-systems framework. In particular, it demonstrated that time-distributed external stimulation can induce multiplication of the dominant oscillatory frequency, providing a plausible mechanistic explanation for the increased incidence of VHFOs and UFOs observed experimentally near epileptogenic tissue.

The GAMU INTERDISCIPLINARY project on mathematical modeling of very and ultra-fast oscillations in EEG has been successfully completed, delivering major advances in understanding pathological high-frequency brain rhythms through phase-shifted synchronization in neuronal networks. During the project, five research articles were published (four in top-decile IF journals), two additional papers were accepted for publication, and several theses, software tools, and international collaborations were completed, significantly strengthening the Nonlinear Dynamics Team and laying the groundwork for future large-scale grants.

Veronika Eclerová received the GAMU Career Restart grant for the project Invariant Descriptors Across Bifurcation Boundaries, aimed at accelerating her research activities following a career break due to maternity leave.

In October 2025, Jakub Záthurecký attended the COUPLED80 international conference in Porto, where he presented some of the team's latest research results. The presentation was devoted to Arnold tongues and newly developed tools for their study. You can find the presentation here
