Long-time behavior of stable-like processes
In this paper, we consider a long-time behavior of stable-like processes. A stable-like process is a Feller process given by the symbol $p(x, \xi)=- i\beta(x)\xi+\gamma(x)|\xi|^{; ; ; \alpha(x)}; ; ; $, where $\alpha(x)\in(0, 2)$, $\beta(x)\in\R$ and $\gamma(x)\in(0, \infty)$. More precisely, we give sufficient conditions for recurrence, transience and ergodicity of stable-like processes in terms of the stability function $\alpha(x)$, the drift function $\beta(x)$ and the scaling function $\gamma(x)$. Further, as a special case of these results we give a new proof for the recurrence and transience property of one-dimensional symmetric stable L\'evy processes with the index of stability $\alpha\neq1.$
