On the convexity of a hitting distribution for discrete random walks
We examine the convexity of the hitting distribution of the real axis for symmetric random walks on Z2 . We prove that for a random walk starting at (0, h), the hitting distribution is convex on [h — 2, oo) fl Z if h > 2. We also show an analogous fact for higher-dimensional discrete random walks...
