The MATHAMSUD240026 is a collaborative research project between researchers from Brazil, Chile, France and Perú.

This project aims to develop an extensive joint research program focused on the concept of‬ ‭expansivity in dynamical systems. This program encompasses multiple lines of research, including‬ ‭the expansivity of discrete groups (such as‬ ‭or‬‭), of flows and their geometry, and actions of‬ ‭general groups. We aim to explore and develop applications in the study of topological dynamics,‬ ‭theoretical computer science and combinatorics, thermodynamic formalism and number theory.‬‭ Additionally, a crucial goal is to establish a robust and interconnected research network for‬ ‭dynamical systems throughout Latin America, promoting new collaborations across Latin‬ ‭American institutions, while simultaneously strengthening collaborations with France. This‬ ‭network will foster exchange opportunities for PhD students, Master’s students, postdocs, and‬ ‭early-career researchers, developing research lines and long-term collaborations among the group‬ ‭members.
