摘要翻译:
我们的目标是解决Fernholz和Karatzas提出的一个问题[On Optime Argulage(2008)Columbia Univ.]:刻画投资者能够以一定概率击败市场组合的初始资本的最小数量,作为市场结构和成熟时间的函数。我们证明了该值函数是非线性偏微分方程的最小非负粘性超解。正如Fernholz和Karatzas[On optimal Argulage(2008)Columbia Univ.],我们不假定存在一个等价的局部鞅测度,而仅仅假定存在一个局部鞅平减指数。

英文摘要:
Our goal is to resolve a problem proposed by Fernholz and Karatzas [On optimal arbitrage (2008) Columbia Univ.]: to characterize the minimum amount of initial capital with which an investor can beat the market portfolio with a certain probability, as a function of the market configuration and time to maturity. We show that this value function is the smallest nonnegative viscosity supersolution of a nonlinear PDE. As in Fernholz and Karatzas [On optimal arbitrage (2008) Columbia Univ.], we do not assume the existence of an equivalent local martingale measure, but merely the existence of a local martingale deflator.
