摘要翻译：
永久美式期权是一种可以随时行使且不到期的金融工具。本文详细研究了这类最流行的衍生品的定价问题，在一个框架内，标的股票的某些属性波动率和股利政策可以在随机的瞬间发生变化，但我们可以预测它们的最终值。在这个假设下，我们可以模拟实际的市场条件，因为大多数相关的事实通常会带来可预测的严重后果。这种潜在风险对永久美式香草期权的影响是显著的：决定公平价格的等式取决于要找到的解决方案。在金融学和物理学的光学下都发现了合理的结果。特别地，在这个问题的整体结果和相变之间建立了一个并行性。

英文摘要：
  Perpetual American options are financial instruments that can be readily exercised and do not mature. In this paper we study in detail the problem of pricing this kind of derivatives, for the most popular flavour, within a framework in which some of the properties |volatility and dividend policy| of the underlying stock can change at a random instant of time, but in such a way that we can forecast their final values. Under this assumption we can model actual market conditions because most relevant facts usually entail sharp predictable consequences. The effect of this potential risk on perpetual American vanilla options is remarkable: the very equation that will determine the fair price depends on the solution to be found. Sound results are found under the optics both of finance and physics. In particular, a parallelism among the overall outcome of this problem and a phase transition is established.
