研究了一类强退化扩散过程的短时渐近行为的大偏差估计。假设由驱动向量场生成的李代数具有幂零结构,我们得到了一个分次大偏差原理,并证明了这些“非常罕见事件”的存在性。特别是第一级与经典的大偏差原理相吻合。
We study the large deviation estimates for the short time asymptotic behavior of a strongly degenerate diffusion process. Assuming a nilpotent structure of the Lie algebra generated by the driving vector fields, we obtain a graded large deviation principle and prove the existence of those "very rare events". In particular the first grade coincides with the classical Large Deviation Principle.
