摘要翻译：
语言和文化多样性是当今世界的一个基本方面。我们研究了三个现代多语言社会----巴斯克地区、爱尔兰和威尔士----它们被赋予了两种语言上遥远的官方语言:$a$，所有人都说，和$B$，双语少数民族说。在这三种情况下，可以观察到使用minoriaritan$B$的衰减，这是多样性丧失的标志。然而，对于“欧洲委员会”来说，避免B$转移的关键因素是它在所有领域的使用。因此，我们用一个进化博弈论模型来研究双语者的语言选择。我们表明，语言种群的动态已经达到了一个进化稳定的平衡，其中一小部分双语人已经转向说$a$。因此，这一均衡抓住了B$使用的下降。为了检验这一理论，我们建立了经验模型，预测每一比例的双语人使用$B$的情况。我们表明，基于模型的预测非常适合巴斯克语、爱尔兰语和威尔士语的观察使用。

英文摘要：
  Language and cultural diversity is a fundamental aspect of the present world. We study three modern multilingual societies -- the Basque Country, Ireland and Wales -- which are endowed with two, linguistically distant, official languages: $A$, spoken by all individuals, and $B$, spoken by a bilingual minority. In the three cases it is observed a decay in the use of minoritarian $B$, a sign of diversity loss. However, for the "Council of Europe" the key factor to avoid the shift of $B$ is its use in all domains. Thus, we investigate the language choices of the bilinguals by means of an evolutionary game theoretic model. We show that the language population dynamics has reached an evolutionary stable equilibrium where a fraction of bilinguals have shifted to speak $A$. Thus, this equilibrium captures the decline in the use of $B$. To test the theory we build empirical models that predict the use of $B$ for each proportion of bilinguals. We show that model-based predictions fit very well the observed use of Basque, Irish, and Welsh.
