摘要翻译：
本文研究了一个随机变量参数化的动态随机优化问题。在运筹学和数学金融学的许多应用中都会出现这样的问题。我们给出了解的存在性和不存在对偶间隙的充分条件。我们的证明使用扩展的动态规划方程，其有效性是在新的放宽条件下建立的，这些条件推广了数学金融学中的某些无套利条件。

英文摘要：
  This paper studies dynamic stochastic optimization problems parametrized by a random variable. Such problems arise in many applications in operations research and mathematical finance. We give sufficient conditions for the existence of solutions and the absence of a duality gap. Our proof uses extended dynamic programming equations, whose validity is established under new relaxed conditions that generalize certain no-arbitrage conditions from mathematical finance.
