Dirichlet heat kernel estimates for fractional Laplacian with gradient perturbation
TL;DR: In this paper, the authors derived sharp two-sided heat kernel estimates for Lb = Δα/2+b⋅∇ in D with zero exterior condition.
Heat Kernel Estimates for Dirichlet Fractional Laplacian
Panki Kim,Zhen-Qing,Renming Song +2 more
TL;DR: In this paper, the authors considered the Dirichlet heat kernel of a non-local Laplacian operator on open sets and established sharp two-sided estimates for the heat kernel.
Journal ArticleDOI
Boundary Harnack Principle for Symmetric Stable Processes
Renming Song,Jang-Mei Wu +1 more
TL;DR: In this paper, the potential-theoretic properties of symmetric α-stable processes (0 < α < 2) were studied. And the boundary Harnack principle for ratios of α-harmonic functions on any open set, identifying the Martin boundary with the Euclidean boundary for open sets with a certain interior fatness property was established.
Journal ArticleDOI
Drift transforms and Green function estimates for discontinuous processes
Zhen-Qing Chen,Renming Song +1 more
TL;DR: In this paper, the authors considered Girsanov transforms of pure jump type for discontinuous Markov processes and showed that under some quite natural conditions, the Green functions of the GPT process are comparable to those of the original process.
Journal ArticleDOI
Two-sided heat kernel estimates for censored stable-like processes
TL;DR: In this article, the exact behavior of the transition density functions of censored α-stable-like processes in C 1,1 open sets in R d, where d ≥ 1 and α ∈ (1,2) was studied.
