Propagation of chaos and large deviations in mean-field models with jumps on block-structured networks
Donald A. Dawson, Ahmed Sid-Ali, Yiqiang Q. Zhao
A system of interacting multiclass finite-state jump processes is analyzed. The model under consideration consists of a block-structured network with dynamically changing multi-col…
Information geometry and Frobenius algebra
Ruichao Jiang, Javad Tavakoli, Yiqiang Zhao
We show that a Frobenius sturcture is equivalent to a dually flat sturcture in information geometry. We define a multiplication structure on the tangent spaces of statistical manif…
Electric Polarization in Inhomogeneous Crystals
Yiqiang Zhao, Yang Gao, Di Xiao
We derive the charge density up to second order in spatial gradient in inhomogeneous crystals using the semiclassical coarse graining procedure based on the wave packet method. It…
An upper bound and criteria for the Galois group of weighted walks with rational coefficients in the quarter plane
Ruichao Jiang, Javad Tavakoli, Yiqiang Zhao
Using Mazur's theorem on torsions of elliptic curves, an upper bound 24 for the order of the finite Galois group associated with weighted walks in the quarter plane $…
Equilibrium customer and socially optimal balking strategies in a constant retrial queue with multiple vacations and -policy
Zhen Wang, Liwei Liu, Yiqiang Q. Zhao
In this paper, equilibrium strategies and optimal balking strategies of customers in a constant retrial queue with multiple vacations and the -policy under two information level…
Weyl Prior and Bayesian Statistics
Ruichao Jiang, Javad Tavakoli, Yiqiang Zhao
When using Bayesian inference, one needs to choose a prior distribution for parameters. The well-known Jeffreys prior is based on the Riemann metric tensor on a statistical manifol…
