Geometrical bounds for the variance and recentered moments

Tongseok Lim, Robert J. McCann

We bound the variance and other moments of a random vector based on the range of its realizations, thus generalizing inequalities of Popoviciu (1935) and Bhatia and Davis (2000) co…

Robust pricing and hedging of options on multiple assets and its numerics

Stephan Eckstein, Gaoyue Guo, Tongseok Lim +1

We consider robust pricing and hedging for options written on multiple assets given market option prices for the individual assets. The resulting problem is called the multi-margin…

Uniqueness and characterization of local minimizers for the interaction energy with mildly repulsive potentials

Kyungkeun Kang, Hwa Kil Kim, Tongseok Lim +1

In this paper, we are concerned with local minimizers of an interaction energy governed by repulsive-attractive potentials of power-law type in one dimension. We prove that sum of…

Optimal Brownian stopping when the source and target are radially symmetric distributions

Nassif Ghoussoub, Young-Heon Kim, Tongseok Lim

Given two probability measures on , in subharmonic order, we describe optimal stopping times that maximize/minimize the cost functional $\mathbb{E} |B_0 -…

Optimal Brownian Stopping between radially symmetric marginals in general dimensions

Nassif Ghoussoub, Young-Heon Kim, Tongseok Lim

Given an initial (resp., terminal) probability measure (resp., ) on , we characterize those optimal stopping times that maximize or minimize the functional…

Dual attainment for the martingale transport problem

Mathias Beiglboeck, Tongseok Lim, Jan Obłój

We investigate existence of dual optimizers in one-dimensional martingale optimal transport problems. While [BNT16] established such existence for weak (quasi-sure) duality, [BHP13…
