This the home page of the ComplexSimplex Group, a group of complex systems based at the Chemical Biology Laboratory of the National Institute of Chemical Physics and Biophysics, Tallinn, Estonia.
Connecting Sciences. We study various systems using a complex systems approach to understand and connect the different processes and mechanisms underlying their emergent properties. You can find information about our activities in this site - feel free to contact us if you have any questions !
Language Dynamics
Our current research is focused on Language Dynamics with the project "Learning Processes in Language Dynamics" supported by the Estonian Research Council through grant PRG1059.
LAST NEWS
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
And here you can find the articles of the collection:

We will present soon 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 made 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 CCS2024 we organized the language complexity satellite COMPILA2024, which was a great success in terms of audience and level os contributions, for details see https://sites.google.com/view/compila2024/home
The next Conference on Complex Systems will take place in Siena, check the updates at
