Uncertainty propagation and dynamic robust risk measures
MR Moresco, M Mailhot… - … of Operations Research, 2024 - pubsonline.informs.org
We introduce a framework for quantifying propagation of uncertainty arising in a dynamic
setting. Specifically, we define dynamic uncertainty sets designed explicitly for discrete …

Set valued hamilton-jacobi-bellman equations
M İşeri, J Zhang - arXiv preprint arXiv:2311.05727, 2023 - arxiv.org
Building upon the dynamic programming principle for set valued functions arising from many
applications, in this paper we propose a new notion of set valued PDEs. The key component …

Dynamic approaches for some time-inconsistent optimization problems
In this paper, we investigate possible approaches to study general time-inconsistent
optimization problems without assuming the existence of optimal strategy. This leads …

Dynamic set values for nonzero-sum games with multiple equilibriums
Nonzero sum games typically have multiple Nash equilibriums (or no equilibrium), and
unlike the zero-sum case, they may have different values at different equilibriums. Instead of …

Conditional systemic risk measures
A Doldi, M Frittelli - SIAM Journal on Financial Mathematics, 2021 - SIAM
We investigate to which extent the relevant features of (static) Systemic Risk Measures can
be extended to a conditional setting. After providing a general dual representation result, we …

Vector-valued robust stochastic control
I Cialenco, G Kováčová - arXiv preprint arXiv:2407.00266, 2024 - arxiv.org
We study a dynamic stochastic control problem subject to Knightian uncertainty with multi-
objective (vector-valued) criteria. Assuming the preferences across expected multi-loss …

Time-consistent conditional expectation under probability distortion
We introduce a new notion of conditional nonlinear expectation under probability distortion.
Such a distorted nonlinear expectation is not subadditive in general, so it is beyond the …

Is a sophisticated agent always a wise one?
J Zhang - SIAM Journal on Financial Mathematics, 2023 - SIAM
For time-inconsistent optimal control problems, a quite popular approach is the equilibrium
approach, taken by sophisticated agents. In this short note, we construct a deterministic …

On the Separability of Vector-Valued Risk Measures
Ç Ararat, Z Feinstein - SIAM Journal on Financial Mathematics, 2024 - SIAM
Risk measures for random vectors have been considered in multiasset markets with
transaction costs and financial networks in the literature. While the theory of set-valued risk …
