Outline of Final Research Achievements

As a mathematical model of language inheritance between generations, we created a simple model with inheritance as a probability event and attempted a simulation. To integrate this model with the game theory model remains to be solved. To show how this model can be put into practice, a case study in language inheritance and educational strategies of Portuguese was carried out in Aichi Prefecture. We also explored a case study in language inheritance and renaissance in the Ryukyu Islands. The model should be upgraded for applicability to the case studies collected.
