English abstract:
We study the path behaviour of a simple random walk C on the 2-dimensional comb lattice that is obtained from Z2 by removing all horisontal edges off the X-axis. We say that a lattice point is covered by C at time n if there is a k ≤ n for which C(k) = (x, y). A set A is covered if each (x, y) ∈ A is covered. Let R n be the largest integer for which [−R n , R n ]2 is covered at time n. Our main result gives an upper and a lower bound for R n . A similar question is investigated for a random walk on the half-plane half-comb lattice.
