报告摘要：
The study of sample path intersections is partially motivated by the needs in mathematical physics. In this talk I will try to describe the large deviations for the self-intersection local times, mutual intersection local times, ranges and the intersection of ranges generated by random walks and Brownian motions. In particular, I will show that the critical dimension for such large deviations is 4.Some unsolved problems and conjectures will be given. Parts of the talk is based on some collaborative works with Richard Bass, Wenbo Li, Peter Morters and Jay Rosen.
