## Reactions: a mathematical model analyses what allows different languages to coexist

A study led by the University of the Balearic Islands proposes a mathematical model to understand quantitatively the impact of ideologies on the coexistence of various languages. The more groups of people with different linguistic preferences mix, the more challenging it becomes for different languages to coexist within the same society, say the authors, whose study is published in the scientific journal *Chaos*. The team says this model could be useful to design policies aimed at preserving minority languages.
