Cooperative colorings of hypergraphs
Xuqing Bai, Bi Li, Weichan Liu +1
Given a class of hypergraphs with the same vertex set , a cooperative coloring of them is a partition …
A tensor optimization algorithm for computing Lagrangians of hypergraphs
Jingya Chang, Bin Xiao, Xin Zhang
The Lagrangian of a hypergraph is a crucial tool for studying hypergraph extremal problems. Though Lagrangians of some special structure hypergraphs have closed-form solutions, it…
A PDE approach for regret bounds under partial monitoring
Erhan Bayraktar, Ibrahim Ekren, Xin Zhang
In this paper, we study a learning problem in which a forecaster only observes partial information. By properly rescaling the problem, we heuristically derive a limiting PDE on Was…
A smooth variational principle on Wasserstein space
Erhan Bayraktar, Ibrahim Ekren, Xin Zhang
In this note, we provide a smooth variational principle on Wasserstein space by constructing a smooth gauge-type function using the sliced Wasserstein distance. This function is a…
Linear quadratic leader-follower stochastic differential games for mean-field switching diffusions
Siyu Lv, Jie Xiong, Xin Zhang
In this paper, we consider a linear quadratic (LQ) leader-follower stochastic differential game for regime switching diffusions with mean-field interactions. One of the salient fea…
