Welcome to the home page of the ComplexSimplex Group!
We study complex systems and are based at the Chemical Biology Laboratory of the National Institute of Chemical Physics and Biophysics, Tallinn, Estonia. Here you can find information about our activities.
You can follow our activities also us on facebook and Bluesky !
Connecting Sciences is the motto of our institute. We study various types of systems using a complex systems and physics-based approach with the goal to understand and connect the different processes and mechanisms underlying their emergent properties. Check this site to find information about our activities and feel free to contact us if you have any questions !
Language Dynamics
Our current research is particularly focused on Language Dynamics, within the project "Learning Processes in Language Dynamics", supported by the Estonian Research Council through grant PRG1059.
We are organizing CompiLa2025, the third edition of the CompiLa interdisciplinary meetings devoted to Complexity in Language. This year CompiLa2025 will be take place on September 4th, 2025, as a satellite meeting of CCS2025, the annual Conference on Complex Systems, which this year will be in Siena, Tuscany.
Check the CompiLa web site for updates!
Marco Patriarca and Els Heinsalu, together with David Sanchez, have completed the editing of the Frontiers in Complex Systems Research Topic "Complexity in Language Variation and Change".
Here is the reference of the editorial: Els Heinsalu, Marco Patriarca, and David Sanchez, Frontiers in Complex Systems, Vol. 2 (2024) doi: 10.3389/fcpxs.2024.1497038

We have presented a contribution at the International Meeting "Fra Italia e Baltico Orientale: incontri culturali, traduttivi e linguistici", October 14-15, Tallinn University
September 26th was the European Day of Languages. It was proclaimed by the Council of Europe on December 6th, 2001, with the goal to inform about the importance of language learning and diversity, increase pluri-lingualism and intercultural understanding, and promote linguistic and cultural diversity in Europe!
We are back from CCS2024, the Conference of Complex Systems 2024 (Exeter, England; September 2-6 2024).
It was a great conference and we are grateful to all the organizers, because we learned a lot, met new and old fantastic colleagues, and presented 5 contributions:
Vivian Dornelas, Celia Anteneodo, Els Heinsalu, Marco Patriarca, An extended Axelrod’s model of innovation spreading and emergence of linguistic diversity.
Renan O. Nunes, Vivian Dornelas, Marco Patriarca, Els Heinsalu, Exploring the dynamics of multiple language coexistence in real networks.
Mikhail Tamm, Els Heinsalu, Stefano Scialla, Marco Patriarca, Thresholds for learning language lead to a variety of stable states in bilingual societies.
Mikhail Tamm, Els Heinsalu, Stefano Scialla, Marco Patriarca, Can language learning be responsible for language coexistence?
Stefano Scialla, Marco Patriarca; Els Heinsalu, Marius Yamakou, Julyan Cartwright, Asymmetry in the distribution of unit properties is the key factor determining the efficiency of collective oscillations in FitzHugh-Nagumo networks.
Compℹ︎La 2024
At the Conference on Complex Sstems CCS2024 in Exeter we have organized the language complexity satellite COMPILA2024! It was a great success in terms of audience and level of contributions. For details, see https://sites.google.com/view/compila2024/home
The next Conference on Complex Systems CCS2025 has been announced officially at the end of CCS2024! It is planned to take place in Siena. For the updates check https://www.congressi.unisi.it/ccs25/
A very beautiful and inspiring conference. Our contribution:
Marco Patriarca, Julyan Cartwright, Els Heinsalu, Stefano Scialla, Marius Yamakou, Asymmetry in the distribution of unit properties is the key factor determining the efficiency of collective oscillations in FitzHugh-Nagumo networks.
Now you can follow us also on Bluesky!
