Time and place: Friday 2:30PM-4PM, B211

## Electrical networks

February 3: Review 2.1 and 2.2 from the Lyons-Peres book and read 2.3

HW problem: Let $B_N=[-N,N]^2$ and let $E_N=\{(x,y): x=N, |y|\le N\}$ the east side of this box. Consider a simple RW started at (0,0) on the lattice where the jump probabilities are $1/4-\epsilon, 1/4, 1/4+\epsilon, 1/4$ for the W, N, E and S directions. Let $\tau_N$ be the hitting time of the boundary of $B_N$. Show that $P(X_{\tau_N}\in E_N)\to 1$
