For any $$\alpha \in (0, 2)$$, a truncated symmetric α-stable process is a symmetric Lévy process in $$\mathbb{R}^{d}$$ with a Lévy density given by $$c|x|^{-d-\alpha} 1_{\{|x| < 1\}}$$ for some constant c. In this paper we study the potential theory of truncated symmetric stable processes in detail. We prove a Harnack inequality for nonnegative harmonic functions of these processes. We also establish a boundary Harnack principle for nonnegative functions which are harmonic with respect to… 

Harnack inequalities for subordinate Brownian motions

In this paper, we consider subordinate Brownian motion  $X$ in $\mathbb{R}^d$, $d \ge 1$,  where the Laplace exponent $\phi$ of the corresponding subordinator satisfies some mild conditions. The

Boundary Behavior of Harmonic Functions for Truncated Stable Processes

For any α∈(0,2), a truncated symmetric α-stable process in ℝd is a symmetric Lévy process in ℝd with no diffusion part and with a Lévy density given by c|x|−d−α1{|x|<1} for some constant c. In (Kim

Potential theory of subordinate killed Brownian motion

Let $W^D$ be a killed Brownian motion in a domain $D\subset {\mathbb R}^d$ and $S$ an independent subordinator with Laplace exponent $\phi$. The process $Y^D$ defined by $Y^D_t=W^D_{S_t}$ is called a

Harnack Inequalities for some Lévy Processes

In this paper we prove Harnack inequality for nonnegative functions which are harmonic with respect to random walks in ℝd. We give several examples when the scale invariant Harnack inequality does

On the Boundary Theory of Subordinate Killed Lévy Processes

Let Z be a subordinate Brownian motion in ℝ d $\mathbb {R}^{d}$ , d ≥ 2, via a subordinator with Laplace exponent ϕ . We kill the process Z upon exiting a bounded open set D ⊂ ℝ d $D\subset \mathbb

Intrinsic Ultracontractivity of Non-local Dirichlet forms on Unbounded Open Sets

In this paper we consider a large class of symmetric Markov processes $X=(X_t)_{t\ge0}$ on $\R^d$ generated by non-local Dirichlet forms, which include jump processes with small jumps of

Weighted Poincaré inequality and heat kernel estimates for finite range jump processes

AbstractIt is well-known that there is a deep interplay between analysis and probability theory. For example, for a Markovian infinitesimal generator $${\mathcal{L}}$$ , the transition density

Global heat kernel estimates for $\Delta+\Delta^{\alpha/2}$ in half-space-like domains

Suppose that $d\ge 1$ and $\alpha\in (0, 2)$. In this paper, we establish by using probabilistic methods sharp two-sided pointwise estimates for the Dirichlet heat kernels of $\{\Delta+ a^\alpha

Intrinsic Ultracontractivity and Ground State Estimates of Non-local Dirichlet forms on Unbounded Open Sets

In this paper we consider a large class of symmetric Markov processes $${X=(X_t)_{t\ge0}}$$X=(Xt)t≥0 on $${\mathbb{R}^d}$$Rd generated by non-local Dirichlet forms, which include jump processes with

Sharp Estimates on the Green Functions of Perturbations of Subordinate Brownian Motions in Bounded $\boldsymbol{\kappa}$-Fat Open Sets

In this paper we study perturbations of a large class of subordinate Brownian motions in bounded κ-fat open sets, which include bounded John domains. Suppose that X is such a subordinate Brownian



Estimates on Green functions and Poisson kernels for symmetric stable processes

One of the most basic and most important subfamily of Levy processes is symmetric stable processes. A symmetric α-stable process X on Rn is a Levy process whose transition density p(t , x − y)

Multidimensional symmetric stable processes

Martin Boundary and Integral Representation for Harmonic Functions of Symmetric Stable Processes

Abstract Martin boundaries and integral representations of positive functions which are harmonic in a bounded domain D with respect to Brownian motion are well understood. Unlike the Brownian case,

Stability of Martin boundary under non-local Feynman-Kac perturbations

Abstract.Recently the authors showed that the Martin boundary and the minimal Martin boundary for a censored (or resurrected) α-stable process Y in a bounded C1,1-open set D with α∈(1,2) can all be

Probabilistic Proof of Boundary Harnack Principle for α-Harmonic Functions

The boundary Harnack principle for fractional Laplacian is now known to hold in Lipschitz domains [5]. It states that if two nonnegative functions, harmonic with respect to a symmetric stable Lévy

Markov processes and martin boundaries part I

The results of this paper were announced in [9]: it is shown how the theory of Martin boundaries can be carried out for certain general types of Markov processes including Brownian motions and Markov
