Название: Lattice Random Walks for Sets of Random Walkers. First Passage Times
Авторы: Lindenberg K., Seshadri V., Shuler K.E.
We have studied the mean first passage time for the first of a set of random walkers to reach a given lattice point on infinite lattices of D dimensions. In contrast to the well-known result of infinite mean first passage times for one random walker in all dimensions D, we find finite mean first passage times for certain well-specified sets of random walkers in all dimensions, except D = 2.
