In other words, even "2+eps" dimensional walks are transient. <br /><br />http://cstheory.stackexchange.com/questions/8058/drunken-birds-vs-drunken-ants-random-walks-between-two-and-three-dimensionsSuresh Venkatasubramanianhttps://www.blogger.com/profile/15898357513326041822noreply@blogger.comtag:blogger.com,1999:blog-3722233.post-90763521785671226692015-03-30T13:46:42.026-05:002015-03-30T13:46:42.026-05:00I really appreciate this intuition.

Before, all I had was a vague idea that 3-dimensions was too "sparse" but 2-dimensions wasn't, which was pretty unsatisfying.<br /><br />Any chance this intuition can generalize to biased random walks?
