英文摘要:
In the past decades, advanced probabilistic methods have had significant impact on the field of finance, both in academia and in the financial industry. Conversely, financial questions have stimulated new research directions in probability. In this survey paper, we review some of these developments and point to some areas that might deserve further investigation. We start by reviewing the basics of arbitrage pricing theory, with special emphasis on incomplete markets and on the different roles played by the \"real-world\" probability measure and its equivalent martingale measures. We then focus on the issue of model ambiguity, also called Knightian uncertainty. We present two case studies in which it is possible to deal with Knightian uncertainty in mathematical terms. The first case study concerns the hedging of derivatives, such as variance swaps, in a strictly pathwise sense. The second one deals with capital requirements and preferences specified by convex and coherent risk measures. In the final two sections we discuss mathematical issues arising from the dramatic increase of algorithmic trading in modern financial markets.

中文摘要:
在过去几十年中,先进的概率方法对金融领域产生了重大影响,无论是在学术界还是在金融行业。相反,金融问题刺激了概率的新研究方向。在这篇调查论文中,我们回顾了其中的一些发展,并指出了一些可能值得进一步调查的领域。我们首先回顾套利定价理论的基础知识,特别强调不完全市场和“现实世界”概率测度及其等价鞅测度所起的不同作用。然后我们关注模型模糊性的问题,也被称为奈特不确定性。我们提出了两个案例研究,其中可以用数学术语处理奈特不确定性。第一个案例研究涉及衍生工具的对冲,如严格意义上的方差互换。第二个问题涉及凸性和一致性风险度量所规定的资本要求和偏好。在最后两部分中,我们将讨论现代金融市场中算法交易急剧增加所带来的数学问题。
