Large and moderate deviations for record numbers in some non-nearest neighbor random walks
Yuqiang Li, Qiang Yao
The deviation principles of record numbers in random walk models have not been completely investigated, especially for the non-nearest neighbor cases. In this paper, we derive the…
Exact moduli of continuity for operator-scaling Gaussian random fields
Yuqiang Li, Wensheng Wang, Yimin Xiao
Let be a centered real-valued operator-scaling Gaussian random field with stationary increments, introduced by Biermé, Meerschaert and Scheffler (Stoc…
Riemann-Liouville processes arising from Branching particle systems
Yuqiang Li
It is proved in this paper that Riemann-Liouville processes can arise from the temporal structures of the scaled occupation time fluctuation limits of the site-dependent (d,α,σ(x))…
Approximations of fractional Brownian motion
Yuqiang Li, Hongshuai Dai
Approximations of fractional Brownian motion using Poisson processes whose parameter sets have the same dimensions as the approximated processes have been studied in the literature…
Multivariate Operator-Self-Similar Random Fields
Yuqiang Li, Yimin Xiao
Multivariate random fields whose distributions are invariant under operator-scalings in both time-domain and state space are studied. Such random fields are called operator-self-si…
Occupation Time Fluctuations of Weakly Degenerate Branching Systems
Yuqiang Li, Yimin Xiao
We establish limit theorems for re-scaled occupation time fluctuations of a sequence of branching particle systems in with anisotropic space motion and weakly degenerate spl…
