On the Covering Time of a Disc by Simple Random Walk in Two Dimensions,Let .(.) denote simple random walk taking values in Z.. It is well known that .(.) is recurrent and hence every finite set is eventually covered by the path of the walk. Let .. be the discrete ball of radius ., ., and let .. be the covering time of ..,.where..

Critical Random Walk in Random Environment on Trees of Exponential Growth,This paper studies the behavior of RWRE on trees in the critical case left open in previous work. For trees of exponential growth, a random perturbation of the transition probabilities can change a transient random walk into a recurrent one. This is the opposite of what occurs on trees of sub-exponential growth.

Some Path Properties of Iterated Brownian Motion,ed Brownian motion” or simply IBM. Funaki (1979) proved that a similar process is related to “squared Laplacian.” Krylov (1960) and Hochberg (1978) considered finitely additive signed measures on the path space corresponding to squared Laplacian (there exists a genuine probabilistic approach, see, e
