摘要:

该文首先在系数有界的条件下, 证明了一类具有退化系数鞅问题解的存在唯一性. 然后借助于函数变换, 指出系数有界条件可以被弱化.

关键词: 鞅问题, 唯一性, 退化系数

Abstract:

In this paper, we first prove the uniqueness of solutions of a kind of martingale problems with degenerate diffusion coefficients in Skorokhod space D[0,+∞)[0,+∞) under some bounded condtions. Then, it is proved that these bounded conditions can be weakened via a transformation.

Key words: Lévy generator, Martingale problem, Uniqueness
