Sharp asymptotics for $N$ -point correlation functions of coalescing heavy-tailed random walk

Jinjiong Yu

We study a system of coalescing continuous-time random walks starting from every site on $Z$ , where the jump increments lie in the domain of attraction of an $I^\pm$ -stable d…

Limit theorems for functionals of linear processes in critical regions

Yudan Xiong, Fangjun Xu, Jinjiong Yu

Let $X = {X_{n} : n \in N}$ be the linear process defined by $X_{n} = \sum_{j = 1}^{\infty} a_{j} ε_{n - j}$ , where the coefficients $a_{j} = j^{- I^^{2}} ℓ (j)$ are constants with $Î²>…
