一般维数下径向对称边值间的最优鞅迁移

Optimal martingale transport between radially symmetric marginals in general dimensions

Tongseok Lim

摘要:

我们确定了\emph{Martingale transport problem}中径向对称初始律和终结律$μ, ν$之间耦合的最佳结构,并证明了优化器的唯一性。这里最优性意味着这样的解将最小化泛函$\E |X-Y|^p$,其中$0<p \leq 1$和维数$d$是任意的。

英文摘要:

We determine the optimal structure of couplings for the \emph{Martingale transport problem} between radially symmetric initial and terminal laws $μ, ν$ on $\R^d$ and show the uniqueness of optimizer. Here optimality means that such solutions will minimize the functional $\E |X-Y|^p$ where $0<p \leq 1$, and the dimension $d$ is arbitrary.
