Three favorite sites occurs infinitely often for one-dimensional simple random walk.
For a one-dimensional simple random walk (S_t), for each time t we say a site x is a favorite site if it has the maximal local time. In this talk, I will present a joint work with Jianfei Shen, which states that with probability 1 three favorite sites occurs infinitely often. Our work is inspired by T贸th (2001), and disproves a conjecture of Erd艖s and R茅v茅sz (1984) and of T贸th (2001). I will try to explain the proof steps.
