    "abstract": "The understanding of language competition helps us to predict extinction and\nsurvival of languages spoken by minorities. A simple agent-based model of a\nsexual population, based on the Penna model, is built in order to find out\nunder which circumstances one language dominates other ones. This model\nconsiders that only young people learn foreign languages. The simulations show\na first order phase transition where the ratio between the number of speakers\nof different languages is the order parameter and the mutation rate is the\ncontrol one.",
