The classical problem of random walks (RW), first formulated by Pearson in 1905 [1, 2], is the question about the probability to find a random walker at certain distance from the start point after n steps, that can occur in general at random direction and random distance with given probability...

Since the set of self-similar asymptotics in addition to Lifshitz-Slyozov’s [1] and Wagner’s [2] ones were found computationally and analytically [3] in the theory of Ostwald ripening, the problem of time corrections to these asymptotics raised and to this day it wasn’t resolved properly...
