NettetA random walk can be thought of as a random process in which a token or a marker is randomly moved around some space, that is, a space with a metric used to compute distance.

NettetPositivity of integrated random walks 197 for all walks with ﬁnite variance, and the results of [6] cover those of [1] and [23]. Note that the ﬁrst version of Dembo et al. [6] had the lower estimate under a less restrictive assumption that, essentially, the tail P(S1 >x)decays exponentially or super-exponentially. 1.3. Nettet1. jul. 2010 · It is well-known that for such random walks P { min 1 ≤ k ≤ n ∑ i = 1 k ξ i 0 ≥ 0 } ∼ c n as n → ∞ for a certain constant c > 0. On the other hand, η 0 ( N) ≍ N 1 / 2 in probability as N → ∞ because of another well-known fact that θ 1 0 belongs to the domain of normal attraction of an α -stable law with exponent 1/2.
