Preimage Regions of Symmetric Separable Maps on the Simplex: Convexity and Barycentric Star-Shapedness

Jilong Xu, Xiaojun Cui

We study preimage regions on the open probability simplex associated with symmetric separable functionally generated maps. The problem is a finite-dimensional geometric question ab…

The Geometry of Admissible Short Selling in Discrete-Time Stochastic Portfolio Theory

Jilong Xu, Xiaojun Cui

While discrete-time Stochastic Portfolio Theory (SPT) provides a robust framework for market analysis, existing work on functional generation has predominantly focused on long-only…

Metric viscosity solutions and distance-like functions on the Wasserstein space

Huajian Jiang, Xiaojun Cui

Viscosity solutions to the eikonal equation |Du|g = 1, known to be exactly distance-like functions, on a non-compact complete Riemannian manifold (M,g) are crucial for understandin…

Viscosity solutions to a Cauchy type problem for timelike Lorentzian eikonal equation

Siyao Zhu, Xiaojun Cui, Tianqi Shi

In this paper, we propose a Cauchy type problem to the timelike Lorentzian eikonal equation on a globally hyperbolic space-time. For this equation, as the value of the solution on…

Multitransition solutions for a generalized Frenkel-Kontorova model

Wen-Long Li, Xiaojun Cui

We study a generalized Frenkel-Kontorova model. Using minimal and Birkhoff solutions as building blocks, we construct a lot of homoclinic solutions and heteroclinic solutions for t…
