Rate of convergence of the Kac-like particle system

Chenguang Liu, Liping Xu

In this paper, we consider the Kac stochastic particle system associated to the spatially homogeneous Boltzmann equation for true hard potentials. We establish a rate of propagatio…

Central limit theorem for a partially observed interacting system of Hawkes processes

Chenguang Liu

We observe the actions of a $K$ sub-sample of $N$ individuals up to time $t$ for some large $K \leq N$ . We model the relationships of individuals by i.i.d. Bernoulli( $p$ )-random vari…

Statistical inference for a partially observed interacting system of Hawkes processes

Chenguang Liu

We observe the actions of a $K$ sub-sample of $N$ individuals up to time $t$ for some large $K < N$ . We model the relationships of individuals by i.i.d. Bernoulli( $p$ )-random variabl…
