一类类稳定过程的鞅问题

The martingale problem for a class of stable-like processes

Richard F. Bass, Huili Tang

摘要:

设$α\in (0,2)$并考虑算子$$L f(x) =\int [f(x+h)-f(x)-1_{(|h|\leq 1)} \nabla f(x)\cdot h] \frac{A(x,h)}{|h|^{d+α}} dh, $$,其中如果$α<1$,则省略$\nabla f(x)\cdot h$项。考虑了与算子$L$对应的鞅问题,并在较弱的条件下证明了函数$A$存在唯一解.

英文摘要:

Let $α\in (0,2)$ and consider the operator $$L f(x) =\int [f(x+h)-f(x)-1_{(|h|\leq 1)} \nabla f(x)\cdot h] \frac{A(x,h)}{|h|^{d+α}} dh, $$ where the $\nabla f(x)\cdot h$ term is omitted if $α<1$. We consider the martingale problem corresponding to the operator $L$ and under mild conditions on the function $A$ prove that there exists a unique solution.
