- Abstract
- In this thesis, we establish sharp two-sided heat kernel estimates for a large class of symmetric Markov processes in $C^{1,\eta}$ open sets for all $t> 0$. The processes are symmetric pure jump Markov processes with jumping kernel intensity
$$\kappa(x, y)\psi(
x-y
)^{-1}
^{-d-\alpha}$$
where $\alpha\in(0,2)$, $\psi$ is an increasing function on $[ 0, \infty)$ with $\psi(r)=1$ on $01$ for $\beta\in[0, \infty]$. A symmetric function $\kappa(x, y)$ is bounded by two positive constants and $
\kappa(x, y)-\kappa(x,x)
\le c_5
^{\rho}$ for $
<1$ and $\rho>\alpha/2$. As a corollary of our main result, we estimates sharp two-sided Green function for this process in $C^{1,\eta}$ open sets.
