Persistence and local extinction for superprocesses in random environments

Zhen-Qing Chen, Yan-Xia Ren, Guohuan Zhao

We consider a super-Brownian motion ${X_{t}, t \geq 0}$ in a random environment described by a centered Gaussian field ${W (t, x), t \geq 0, x \in R^{d}}$ whose correlation funct…

Quantitative homogenization on time-dependent random conductance models with stable-like jumps

Xin Chen, Zhen-Qing Chen, Takashi Kumagai +1

We establish quantitative homogenization results for time-dependent random conductance models with stable-like long range jumps on $Z^{d}$ , where the transition probability from $x$ …

Dirichlet problem for diffusions with jumps

Zhen-Qing Chen, Jun Peng

In this paper, we study Dirichlet problem for non-local operator on bounded domains in $R^{d}$ $$ {\cal L}u = {\rm div}(A(x) \nabla (x)) + b(x) \cdot \nabla u(x) + \int_{{\…
