Abstract:
We establish a small time large deviation principle and a Varadhan type asymptotics for Brownian motion with singular drift on $\mathbb {R}^d$ with $d\geq 3$ whose infinitesimal generator is $\frac 12 \Delta + \mu \cdot \nabla$, where each $\mu _i$ of $\mu = (\mu _1, \ldots , \mu _d)$ is a measure in some suitable Kato class.References
