摘要:
We establish both the lim sup and the lim inf law of the iterated logarithm (LIL) for the capacity of the range of a simple random walk in any dimension d >= 3. While for d >= 4, the order of growth in n of such LIL at dimension d matches that for the volume of the random walk range in dimension d - 2, somewhat surprisingly this correspondence breaks down for the capacity of the range at d = 3. We further establish such LIL for the Brownian capacity of a three-dimensional Brownian sample path and novel, sharp moderate deviations bounds for the capacity of the range of a four-dimensional simple random walk.
