This paper examines the convergence of nearest-neighbor random walks on convex subsets of the latticesℤd. The main result shows that for fixedd, O(γ2) steps are sufficient for a walk to “get random,” where γ is the diameter of the set. Toward this end a new definition of convexity is introduced for subsets of lattices, which has many important properties of the concept of convexity in Euclidean spaces.
