We encourage researchers to participate in the FRCCS 2024 <https://iutdijon.u-bourgogne.fr/ccs-france/> workshops to share their insights and foster interdisciplinary collaborations in the study of complex systems. *Workshops* · Modeling Cities and Regions as Complex and Evolving Systems · Beauty in Complexity · Network Sparsification & beyond *Important dates* Submission Deadline: *April 14, 2024* Final Decisions Released:* April 17, 2024* Camera-Ready Deadline: *April 30, 2024* *1) **Modeling Cities and Regions as Complex and Evolving Systems* <https://iutdijon.u-bourgogne.fr/ccs-france/workshop-on-modeling-cities-and-regions-as-complex-and-evolving-systems/> Cities consist of interacting entities, such as people and infrastructure, and exhibit emergent properties, which appear additionally to the sum of the isolated properties. This makes cities a prime example of complex systems. Accordingly, complexity theories and methods are particularly relevant to their study. By focusing on the commonalities that underpin urban systems, the workshop seeks to foster interdisciplinary dialogue and explore novel approaches to studying cities as complex entities. *More info at: * *https://iutdijon.u-bourgogne.fr/ccs-france/workshop-on-modeling-cities-and-r... <https://iutdijon.u-bourgogne.fr/ccs-france/workshop-on-modeling-cities-and-regions-as-complex-and-evolving-systems/> *Workshop chair* *Daniela Cialfi - NRCouncil of Italy - **danielacialfi@gmail.com* <danielacialfi@gmail.com> *2) **Beauty in Complexity* <https://iutdijon.u-bourgogne.fr/ccs-france/beauty-in-complexity/> The Beauty in Complexity exhibition invites researchers to share the visual wonders of their work with a wide and diverse audience. Whether it's a photograph, diagram, visualization, or montage, we encourage submissions that evoke curiosity and wonder. We seek captivating visuals showcasing the beauty found within complex systems research.

This workshop aims to bring together researchers working on the broad theme of network simplification and discuss graph reduction methods and their applications.
